A heterogeneous organic-inorganic hybrid durable nanocatalyst gamma-Al2O3@Silane-TMG was prepared by covalently functionalization of nano-gamma-Al2O3 through anchored 3-chloropropyl- trimethoxysilane with 1,1,3,3-tetramethylguanidine (TMG). The structure of the catalyst was characterized by various techniques including FT-IR, XRD, SEM, EDX and TGA analyses. The synthesized nanocatalyst was successfully used in an efficient and green four-component synthesis of pyrazolopyranopyrimidine derivatives using ethyl acetoacetate, hydrazine hydrate, arylaldehydes and barbituric acid (or thiobarbituric acid) in H2O at 40 oC. This practical method produced the desired products at reduced reaction times (10-25 min) and high to excellent yields (85-98%). The main advantages of this practical method are the use of heterogeneous basic nanocatalyst, simple work-up procedure with no need to chromatographic purification, affording highly selective conversion and recyclability of the catalyst which could be used in 5 cycles with only a small decrease in its activity.

Coal fluidity is an important parameter in coal blending techniques for coke making because it strongly influences coke qualities. On the other hand, recently, the amount of high fluidity coal has been limited. To cope with this problem, caking additive method which improves fluidity of coal has been developed and commercialized. However, since tight supply of high fluidity coal is anticipated in the future, it is of great importance to develop more effective caking additive. Therefore, in this study, we investigated effect of 11 kinds of polyaromatic hydrocarbons which include oxygen, sulfur and nitrogen containing compounds on coal fluidity in order to search for more effective chemical substances. The additives were added to low fluidity coal, and fluidity analyses were carried out according to the Gieseler plastometer method. Addition of sulfur and oxygen containing compounds lowered fluidity of coal, whereas addition of aromatic amines enhanced fluidity of coal. Coal fluidity ameliorated with increasing the molecular weight of aromatic amine, and N,N’-di-2-naphthyl-1,4-phenylenediamine (DNPD) was the most effective aromatic amine in this study. Carbonization tests in an electric furnace were conducted to investigate an effect of DNPD on coke strength. As a result of adding only 1 wt% DNPD, fluidity of blended coal and coke strength (Drum Index) were highly improved.

Organo-radical catalysts have recently attracted great interest, and the development of this field can be expected to broaden the applications of organocatalysis. Herein, the first example of a radical-generating system is reported that does not require any photoirradiation, radical initiators, or preactivated substrates. The oxidative C-C-bond cleavage of 2-substituted cyclohexanones was achieved using an azolium salt and a hydroquinone as co-catalysts. A catalytic mechanism was proposed based on the results of diffusion-ordered spectroscopy and cyclic voltammetry measurements, as well as computational studies.

We report a set of electrochemically regulated protocols for the divergent synthesis of ketones and beta-keto esters from the same beta-hydroxycarboxylic acid starting materials. Enabled by electrochemical control, the anodic oxidation of carboxylic acids proceeded in either a one-electron or a two-electron pathway, leading to a 1,4-aryl transfer or a semipinacol-type 1,2-group transfer product with excellent chemoselectivity. The 1,4-aryl transfer represents an unprecedented example of carbon-to-oxygen group transfer proceeding via a radical mechanism. In contrast to previously reported radical group transfer reactions, this 1,4-group transfer process features the migration of electron-rich aryl substituents. Furthermore, with these chemoselective electrochemical oxidation protocols, a range of ketones and beta-keto esters including those possessing a challenging-to-access medium-sized ring could be synthesized in excellent yields.

Recommanded Product: 90-44-8. The Name is Anthrone. Through research, I have a further understanding and discovery of 90-44-8.

A new aromatic diamine, 10,10-bis [4-(4-amino-2-pyridinoxy)phenyl]-9(10H)-anthracenone (BAPPA) was synthesized from anthrone as the starting material, and the corresponding pyridine- and anthrone-containing poly(ether amide)s (PEAs) were prepared from BAPPA with various aromatic diacid chlorides via a low-temperature solution polycondensation. The resulting PEAs having number-average molecular weights (M-n) of 29,500-33,400 g/mol with the polydispersity index ranged from 1.75 to 1.84, were all amorphous, and displayed excellent thermal stability with the glass transition temperatures of 263-355 degrees C, the temperatures of 415-441 degrees C at 5% weight loss and the higher than 50% residues at 800 degrees C in nitrogen. These new PEAs were soluble in polar solvents such as N-methyl-2-pyrrolidone, N,N-dimethylacetamide and pyridine, even almost in tetrahydrofuran at room temperature and could form transparent, strong and flexible films with tensile strengths of 84-97 MPa, tensile moduli of 2.1-3.2 GPa and elongations at break of 4-13%. Also, the present PEAs exhibited high optical transparence with the UV cutoff wavelength in the 342-362 nm range, and 83-90% transmittance at 500 nm. These results indicated the introduction of anthrone and pyridine groups into the backbone could improve the solubility and transparence of polyamides.

The Name is Benzophenone. Through research, I have a further understanding and discovery of 119-61-9.

Interest in the potential human health of semi-volatile organic chemicals (SVOCs) in indoor and outdoor environments has made the exposure assessment and source appointment a priority. In this study, paired indoor and outdoor atmospheric fine particle (PM2.5) samples were collected from 15 homes representing five typical urban cities in southern China. Four typical SVOCs, including 16 congeners of polycyclic aromatic hydrocarbons (PAHs), 13 congeners of organophosphorus flame retardants (OPFRs) and 8 congeners of polybrominated diphenyl ethers (PBDEs), as well as tetrabromobisphenol A (TBBPA) and its three debrominated congeners were analyzed. The highest total concentrations were found for OPFRs, followed by PAHs, PBDEs, and TBBPA. The indoor concentrations of two alkyl-OPFR isomers, tributylphosphate (TBP) and tris (2-butoxyethyl) phosphate (TBEP), were 4.3 and 11 times higher, respectively, than those of outdoors (p < 0.05). Additionally, the ratios of indoor to outdoor concentrations of alkyl-OPFR isomers varied greatly, suggesting that these compounds originated mainly from different household goods and products used in individual homes. The outdoor concentrations of PAHs and highly brominated PBDEs (BDE-209) typically exceeded the indoor concentrations. Significant correlations were also found between indoor and outdoor PM2.5 samples for PAHs and BDE-209, indicating that outdoor sources such as vehicle exhausts and industrial activities strongly influence their atmospheric occurrence. Additionally, the concentrations of debrominated TBBPA derivatives were higher than those of TBBPA in over 33% of both indoor and outdoor air particle samples. Nevertheless, our results indicated that inhalation exposure to typical SVOCs posed no non-carcinogenic risks to the human body. Although we observed notable differences in the sources, occurrences, and distributions of typical SVOC congeners, more studies using matched samples are still needed to unambiguously identify important indoor and outdoor sources in order to accurately assess the contributions of different sources and the associated human exposure risks.

The polysaccharide of yam was extracted by hot water method and purified by column chromatography. The physicochemical properties of Chinese yam polysaccharide were analyzed by UV, IR, GPC, 1D-NMR and 2D-NMR spectra. The results showed that Chinese yam polysaccharide had alpha-D-Gluc-(1 -> 4) glycoside bond, and the C2 hydroxyl group was replaced by ethoxyl group. The average molecular weight was determined to be 7.28 x 104. It showed that The scavenging effect of yam polysaccharide on hydroxyl radicals was similar to VC. The sulfated polysaccharide (S-P), phosphorylated polysaccharide (P-P), carboxymethylated polysaccharide (C-P) and acetylated polysaccharide (A-P) were identified by IR and NMR. The results showed that P and its derivatives showed good antioxidant activity. Especially, their scavenging ability to hydroxyl radicals reached the level of VC. This laid a theoretical foundation for the development of yam polysaccharide-related foods.

Chiral hyperbranched polymers (HBP) containing cinchona alkaloids were synthesized using a Mizoroki-Heck (MH) coupling polymerization reaction between a cinchona squaramide dimer and tri- or tetrasubstituted aromatic iodides. This is a new type of polymeric chiral organocatalyst. We found that the as-obtained chiral HBPs show excellent catalytic activity in the asymmetric Michael reaction. Almost perfect enantioselectivity (>99% ee) was achieved in the reaction of beta-ketoester and trans-beta-nitrostyrene. The three-dimensional network structure of the chiral HBPs is structurally robust and can be reused for further reaction without any loss in their catalytic activity. (C) 2019 Elsevier Inc.

In the present study, different derivatives of thymol (1) viz. hydrazide (2), oxadiazole thiol (3), triazole thione (4), hydrazones (5-7), and beta-lactams (8-10) were synthesized. All synthesized compounds were identified and characterized using elemental analysis, UV-Visible, H-1 NMR, C-13 NMR, and IR spectroscopic techniques. Synthesized thymol derivatives were evaluated for antifungal potential against phytopathogenic fungi Fusarium moniliforme, Rhizoctonia solani, and Dreschlera maydis of maize in comparison to recommended standards in terms of percent inhibition and ED50 values. Thymol was more effective as compared to its derivatives against all three tested fungi. Hydrazones (5-7) and beta-lactams (8-10), having m-NO2 substituted phenyl ring (6, 9), were less effective as compared to o-NO2 and p-NO2 analogs against F. moniliforme and R. solani, however, the reverse trend was observed against D. maydis. Thymol and its derivatives were also tested for insecticidal activity against stored grain (chickpea) insect Callosobruchus chinensis and various parameters viz. egg laying, adult emergence, and grain damage were recorded and compared. Compounds having oxadiazole thiol (3) and triazole thione (4) moiety showed promising effects against insect C. chinensis.
