Application In Synthesis of Benzophenone

Propylene polymerization titanium-magnesium catalysts (TMCs) were synthesized from different magnesium compounds with diphenylketone (DPK) as the internal donor. The catalysts differed by an order of magnitude and more in the content of titanium and donor, activity, specific surface area and pore size. Sizes of MgCl2 crystallites with 110 or 104 lateral cuts were calculated from the Ti/Mg and DPK/Mg values. For highly active TMCs the composition, XRD and specific surface area were in agreement with the MgCl2 crystallites with 104 lateral cuts, TiCl4 adsorption on one magnesium ion and elongated in the 001 direction. For low-activity TMCs obtained by reacting Mg with BuCl, the sizes of MgCl2 crystallites in different directions were close. Activity of the catalysts was inversely proportional to the crystallite size calculated from the TMC composition. This dependence was preserved for the catalysts obtained via the substitution of ketone by phthalate.

Photoredox catalysis in recent years has manifested a powerful branch of science in organic synthesis. Although merging photoredox and metal catalysts has been a widely used method, switchable heterogeneous photoredox catalysis has rarely been considered. Herein, we open a new window to use a switchable heterogeneous photoredox catalyst which could be turned on/off by changing a simple stimulus (O-2) for two opponent reactions, namely, oxidative and protodecarboxylation. Using this strategy, we demonstrate that Au@ZnO core-shell nanoparticles could be used as a switchable photocatalyst which has good catalytic activity to absorb visible light due to the localized surface plasmon resonance effect of gold, can decarboxylate a wide range of aromatic and aliphatic carboxylic acids, have multiple reusability, and are a reasonable candidate for synthesizing both aldehydes/ketones and alkane/arenes in a large-scale set up. Some biologically active molecules are also shown via examples of the direct oxidative and protodecarboxylation which widely provided pharmaceutical agents.

Safety of Benzophenone. I found the field of Science & Technology – Other Topics very interesting. Saw the article Ahmed implant coated with poly(2-methacryloyloxyethyl phosphorylcholine) inhibits foreign body reactions in rabbit eyes published in 2021.0, Reprint Addresses Kee, C (corresponding author), Sungkyunkwan Univ, Dept Ophthalmol, Samsung Med Ctr, Sch Med, Seoul, South Korea.. The CAS is 119-61-9. Through research, I have a further understanding and discovery of Benzophenone.

Purpose Wound healing after Ahmed glaucoma valve (AGV) implantation often entails fibrosis as a foreign body reaction to the silicone plate. Poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) forms an antifouling surface that inhibits fibrosis during wound healing. In this study, we aimed to compare the effects of the implantation of AGV coated with PMPC (wPMPC) versus AGV without PMPC (woPMPC) in rabbits. Methods Six New Zealand White rabbit does underwent AGV implantation in both eyes. For each rabbit, one eye was randomly selected for implantation of AGV wPMPC and a conventional AGV (woPMPC) was implanted in the contralateral eye. Gross conjunctival vascularity was compared between the two groups at the first, second, and fourth weeks after surgery. The eyes were enucleated in four weeks and subjected to staining with hematoxylin and eosin and Masson’s trichrome stain. The fibrosis and inflammation status among the eye samples were compared by measuring the thickness of the fibrotic walls and counting the number of chronic inflammatory cells around the AGV. Counting of inflammatory cells and measuring fibrotic wall thickness were done in a blinded method to eliminate observer bias. Statistical analysis was performed using the Mann-Whitney U test. Results Gross and histological examinations revealed no toxic effects of PMPC. There were no apparent differences in overall conjunctival vascularity between the two groups at weeks 1, 2, and 4 after surgery. The average inflammatory cell counts were 14.3 5.8 per slide and 27.3 +/- 8.6 per slide in the wPMPC and woPMPC groups, respectively (p = 0.037). The average thicknesses of the fibrotic wall were 57.9 +/- 11.3 mu m and 81.5 +/- 21.3 mu m in the wPMPC and woPMPC groups, respectively (p = 0.025). Conclusion Compared to the woPMPC group, the number of inflammatory cells and fibrosis were significantly decreased in the wPMPC group.

Fe3O4@SiO2-Pr@L-proline magnetic nanoparticles were synthesized and their efficiency as nanocatalyst for the synthesis of new derivatives of bis dapsone derived dihydropyridines via one-pot three-component condensation reaction of various aromatic aldehydes, dimedone and dapsone in aqueous media was investigated. The products were characterized by H-1 NMR, C-13 NMR, FT-IR and CHNS analysis. These bis-drugs present high antibacterial activities against both gram-negative (Pseudomonas aeruginosa and Escherichia coli) and gram-positive (Micrococcus luteus and Bacillus subtilis) bacteria, which are in general more sensitive to compounds with halogen or hydroxyl functional groups.

The loss of neurons is strongly correlated with aging and aging-associated disorders. In this study, cell viability assays and mitochondrial function were performed to evaluate the effect of new spiro-pyrazole derivatives, prepared from aldehydes and 3-amino-1-phenyl-2-pyrazolin-5-one, on neuroprotection in an in vitro model of dopaminergic cell death induced by 1-methyl-4-phenylpyridinium (MPP+). The percentages of neuroprotection by derivatives were found between 21.26% and 52.67% at selected concentrations (10-50 mu M) with compound 4d exerting the best neuroprotective effect. The results show that the studied spiropyrazolones perform important roles in dopaminergic neuroprotection and can be used for potential new therapies in the treatment of neurodegenerative disorders including Parkinson’s disease.

Background: Dementia, as a global public health problem, is becoming increasingly serious. As a precursor of dementia, mild cognitive impairment (MCI) plays an important role in the diagnosis and prevention of dementia. Recent studies have found a correlation between gamma-glutamyl transferase (GGT) levels and cognitive function in men. The relationship between GGT levels and cognitive function in women remains unclear because GGT activity and expression differ between the sexes. Method: We recruited a total of 2,943 Chinese women from Jidong and Taian in 2019. We grouped the participants according to GGT levels, diagnosed MCI using the Montreal Cognitive Assessment (MOCA) scale, and modeled the study outcomes using logistic regression to explore the relationship between GGT level and MCI. We also analyzed the interaction of obesity, sleep duration, and hyperuricemia with GGT in the development of MCI. Results: The prevalence of MCI increased with increasing GGT level, from the lowest quartile to the highest quartile of GGT: 8.4% (66/786), 14.2% (119/840), 17.6% (108/613), and 21.4% (151/704), respectively. At the same time, as GGT levels increased, so did the risk of MCI. In the fully adjusted model, compared with those for participants in the lowest GGT quartiles, the odds ratios (ORs), and 95% confidence intervals (CIs) for MCI for participants in the second, third, and fourth GGT quartiles were 1.49 (1.04-2.12), 1.53(1.06-2.21), and 1.88 (1.33-2.65), respectively. The risk of developing MCI was further increased in people with high GGT levels who were obese (OR = 1.96, 95% CI: 1.39-2.76, P < 0.001), slept less (OR = 1.91, 95% CI: 1.35-2.71, P < 0.001), had high levels of uric acid (OR = 1.55, 95% CI: 1.03-2.32, P < 0.001), or after menopause (OR = 2.92, 95% CI: 2.07-4.12, P < 0.001). Conclusion: We found that MCI is more common in women with elevated GGT levels, so GGT could be a potential diagnostic marker for MCI. Meanwhile, our findings indicated that women with high GGT levels had an increased risk of MCI when they were obese, sleep deprived, had high serum uric acid (SUA) levels or underwent menopause.

Cinchona-based chiral hyperbranched polymers (HBPs) were designed and successfully synthesized via the Mizoroki-Heck (MH) coupling reaction. AB(2) and A(2)B-type chiral monomers were prepared from cinchona squaramide derivatives, where A (vinyl) reacted only with B (iodophenyl) under MH reaction conditions. The chiral HBPs obtained by the MH polymerization contained cinchona squaramide moieties and demonstrated excellent diastereoselectivity and enantioselectivity in asymmetric Michael addition reactions of methyl 2-oxocyclopentanecarboxylate and trans-beta-nitrostyrene. These newly designed HBPs were structurally robust and could be reused for further reaction without losing their catalytic activity. (C) 2020 Elsevier Ltd. All rights reserved.

Liquid phase tandem Knoevenagel-Michael condensation of various aromatic and heteroaromatic aldehydes with barbituric acid or 2-thiobarbituric acid and malononitrile was studied in a one-pot three-component reaction. For the first time, TMDP was employed as a safe and efficient solvent and/or catalyst in the liquid and aqueous ethanol medium, respectively, for the practical and eco-friendly Knoevenagel-Michael condensation. The reactions were carried out by using greener procedures, including a) the use of TMDP as an N-heterocycle organocatalyst in a green medium including water and ethanol (1:1 v/v) at reflux temperature, and b) the use of TMDP as a dual solvent-catalyst at 65 degrees C in the absence of any solvent. High to excellent yields of the desired pyrano[2,3-d] pyrimidinones were obtained under the two earlier mentioned conditions. The current methodologies have advantages, including (a) avoiding hazardous, toxic, volatile, and flammable materials and solvents, (b) avoiding tedious processes, harsh conditions, and multiple steps for the preparation of catalysts, (c) using a less toxic and noncorrosive catalyst, (d) minimizing hazardous waste generation and simple workup process, and (e) high recyclability of TMDP. Another important result of this work is that the TMDP can be a promising alternative for toxic, volatile, and flammable base reagents such as piperidine and triethylamine in liquid phase organic syntheses owing to its unique properties such as being less toxic, nonflammable, and nonvolatile, and having a low melting point, broad liquid range temperature, high thermal stability, and safe handling and storage.

A new Zr-based MOF, namely, UiO-66-Urea, was prepared through polymerization between the 2-aminoterephthalate linkers of UiO-66-NH2 MOF and 1,4-phenylene diisocyanate under mild reaction conditions. Post-synthetic coating of UiO-66-Urea with choline chloride (ChCl), as easily available, inexpensive, and nontoxic reagent, under thermal and solvent-free conditions resulted in in-situ formation of a deep-eutectic solvent-like on the UiO-66-Urea’s surface, called here ChCI@UiO-66-Urea. The presence of Zr6O4(OH)(4) nodes and urea groups may capable of strong hydrogen bond formation with ChCl. The porous and bioinspired ChCl@UiO-66-Urea was characterized using FT-IR, powder XRD, SEM, EDX elemental mapping, TGA, and BET surface area measurements. Choline chloride-coated UiO-66-Urea was successfully promoted one-pot three-component synthesis of 2-amino-4H-chromenes, as biologically active heterocycles, through reactions of aldehydes, malononitrile, and alpha-naphthol or 4-hydroxycoumarin under solvent-free conditions. The catalytic activity of the respective solid was superior than UiO-66, UiO-66-NH2, UiO-66-Urea, and even ChCl-2Urea due to synergistic effect between actives sites of UiO-66-Urea and ChCl. The reaction includes a consecutive three-step Knoevenagel condensation/Michael addition/cydization mechanism. (C) 2020 Elsevier B.V. All rights reserved.

A (bis)azolium salt [L1-H-2]Br-2 (5), synthesized following multistep procedures, was realized to be a suitable platform for accessing the bis(NHC) ligand supported heterobimetallic Ir-III-M (M = Pd-II/Au-I) complexes via a sequential metalation strategy for their potential catalytic applications in one-pot tandem organic transformations. First, the reaction of 5 with 0.5 equiv of [Ir(Cp*)Cl-2](2) selectively yielded a monometallic Ir-III complex 6, which was further metalated using Pd(OAc)(2)/NaOAc to afford the heterobimetallic Ir-III-Pd-II complex 7. On the other hand, complex 6 was reacted with Ag2O, followed by transmetalation with [Au(SMe2)Cl] in a one-pot manner, to yield the Ir-III-Au-I complex 8. Further, the related homobimetallic Ir-III and Pd-II complexes 9 and 10, respectively, have also been synthesized directly from [L1-H-2]Br-2. All the homo/heterobimetallic complexes have been well-characterized by multinuclear NMR spectroscopy, ESI-mass spectrometry, and via single-crystal X-ray diffraction studies of the complexes 7, 8, and 10. The heterobimetallic Ir-III-Pd-II complex 7 has been tested as a catalyst for three one-pot tandem catalytic reactions: (a) Suzuki-Miyaura coupling and transfer hydrogenation of ketones, (b) hydrodefluorination and transfer hydrogenation of ketones, and (c) hydrodehalogenation and transfer hydrogenation of imines. Importantly, the catalytic activity of heterobimetallic complex 7 in the above-mentioned reactions was found to be better than the mixture of their corresponding homobimetallic counterparts 9 and 10, keeping the concentration of the metal centers constant. These observations affirm some sort of cooperativity between the two metal centers (Ir and Pd) connected via a single ligand frame in 7 when catalytic activity is concerned, which thus constitutes a superior catalytic system than that of the cases where two separate metal complexes (hence, the two metal centers are not connected by a single ligand framework) are used.
