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

The advent of transfer hydrogenation and borrowing hydrogen reactions paved the way to manipulate simple alcohols in previously unthinkable manners and circumvented the need for hydrogen gas. Analogously, transfer hydrocarbylation could greatly increase the versatility of tertiary alcohols. However, this reaction remains unexplored because of the challenges associated with the catalytic cleavage of unactivated C-C bonds. Herein, we report a rhodium(I)-catalyzed shuttle arylation cleaving the C(sp(2))-C(sp(3)) bond in unstrained triaryl alcohols via a redox-neutral beta-carbon elimination mechanism. A selective transfer hydrocarbylation of substituted (hetero)aryl groups from tertiary alcohols to ketones was realized, employing benign alcohols as latent C-nucleophiles. All preliminary mechanistic experiments support a reversible b-carbon elimination/migratory insertion mechanism. In a broader context, this novel reactivity offers a new platform for the manipulation of tertiary alcohols in catalysis.

Covalent organic frameworks (COFs) can be rationally designed with desired physicochemical properties for a far-ranging application in catalytic systems. Herein, a biguanide-functionalized covalent organic framework was designed and prepared via N-alkylation reaction, exhibiting a granular aggregate structure with high specific surface area. The biguanide-decorated DG-COF can be used as a highly efficient basic catalyst for the Knoevenagel condensation and Knoevenagel-Michael-cyclocondensation reaction. The present methodology is of excellent yields, short reaction times and simple operational procedure. DG-COF catalytic performance does not change after eight-times regeneration.

Recommanded Product: 90-44-8. I found the field of Energy & Fuels; Materials Science very interesting. Saw the article Effects of Different Ring-Expanded Strategies for Nonfullerene Acceptors in Organic Photovoltaics under Donor and Acceptor Excitation published in 2021, Reprint Addresses Sun, GY (corresponding author), Yanbian Univ, Fac Sci, Dept Chem, Yanji 133002, Jilin, Peoples R China.; Sun, GY (corresponding author), Jilin Univ, Zhuhai Coll, Fac Chem Engn & New Energy Mat, Zhuhai 519041, Guangdong, Peoples R China..

The ring-expanded strategy in nonfullerene acceptors (NFAs) with the acceptor-donor-acceptor backbone has been reported to be an effective method to improve the fill factor (FF), open circuit voltage (VOC), and short circuit current (JSC) simultaneously in organic photovoltaics. However, design control is still missing in the ring-expanded strategy, and is urgently needed to further develop the origins and rules. To give insight into this strategy, a detailed theoretical study of the ring-expanded mechanism is performed on the systems comprising different 9,9 ‘-bifluorenylidene-based cores and 1,1-dicyanomethylene-3-indanone group. Some main parameters involved in photoelectric conversion mechanism under the donor excitation (DE) and/or acceptor excitation (AE) are assessed by changing the position and size of ring-expanded modes. The results show that the external ring-expanded modes can not only maintain the original advantage as much as possible, variations in sizes and positions also offer them an opportunity to regulate the aforementioned parameters systematically, leading to better improvement regardless of AE or DE. Thus, the steady improvement in performance mentioned previously is the key to overcoming the negative correlation among FF, VOC, and JSC. This insight and discovery of the ring-expanded strategy provides new design approaches for the next generation of NFAs.

Defect engineering of nanomaterials has emerged as a promising approach to improve their performance for pollutant removal. However, various nanomaterial defects play variant roles in environmental applications. It is still a challenge to construct multiple defects of composite materials into advantageous aggregates to deal with complicated matrix pollution. In this work, we investigated a series of three-dimensional defect-optimized aerogels (3D DOAs) of graphene oxide (GO) with a covalent triazine framework (CTF) for improved adsorption and photoregeneration performance via tailoring duet carbon and nitrogen defects. Using chemical reduction, carbon defects in GO were gradually repaired and nitrogen defects in CTF were created simultaneously. The carbon defect engineering generated additional nonpolarized electron-depleted sites in GO of 3D DOA for increased adsorption capacities (2417 mu mol/g for benzophenone, 2209 mu mol/g for 4-hydroxybenzophenone, 1957 mu mol/g for 2,2′,4,4′-tetrahydroxybenzophenone). Meanwhile, increasing nitrogen defects of the CTF in 3D DOA would produce midgap states for an extended absorption range of visible light and increased photocatalytic activity to remove adsorbed pollutants. The enhanced adsorption and the superior photocatalytic regeneration soundly corroborated that the performance of 3D DOA was improved effectively by the defect optimization strategy. Moreover, the high stability of 3D DOA and its practical usage were verified in a real water matrix with a 7-day cycle test. The present work highlights an approach of defect optimization for development of a solar-driven, self-regenerative adsorbent for water purification with high efficiency.

It is found that free radicals of (OH)-O-center dot would be generated in KOH solutions at elevated temperatures according to the results of fluorescence analysis. Five kinds of radical inhibitors (tert-butylphenol-containing reagents, 4-amino-tempo, benzophenone, phenothiazine and N-phenyl-1-naphthylamine) were employed as the dopant, separately, to prepare anion exchange membranes (AEMs) based on poly(4-vinylbenzylchloride-styrene). The investigaions on the properties of the prepared AEMs indicate that more radicals might be produced during the degradation of the AEMs via chain propagation reactions. Moreover, the influences of the radical inhibitors on the degradation of the AEMs in 8 M KOH solutions at 80 degrees C are quite different although all these inhibitors could react with (OH)-O-center dot radicals. Therein the radical inhibitors o-, m-, p-tert-butylphenols could effectively enhance the chemical stability of the AEMs. However, when the phenol-containing inhibitors have a large substituent group in its benzene ring, the membranes tend to be brittle during the stability test.

The enantioselective aminocatalytic alpha-chlorination of aldehydes is a challenging reaction because of its tendency to proceed through neutral intermediates in unselective pathways. Herein we report the rational shift to a highly selective reaction pathway involving charged intermediates using hexafluoroisopropanol as solvent. This change in mechanism has enabled us to match and improve upon the yields and enantioselectivities displayed by previous methods while using cheaper aminocatalysts and chlorinating agents, 80-95% less amount of catalyst, convenient temperatures, and shorter reaction times.

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.

Flexible, lightweight and practical luminous fibers have aroused great interest in the field of smart textiles. In this study, we report flexible aggregation induced emission luminogen (AIEgen) fibers which can be produced in a continuous and large-scale way. Fluorescent nanofibers prepared by conjugate electrospinning are wrapped on the surface of flexible core fiber to form a skin-core AIEgen fiber. The electrospinning parameters including spinning concentration, traction rate, spinning rate and tetraphenylethylene (TPE) concentration were designed and optimized via the non-interactive orthogonal experimental design. The optimized flexible AIEgen fiber retains the excellent mechanical properties of core fiber and is equipped with the fluorescence properties of the wrapped fluorescent nanofibers. In addition, the fabricated AIEgen fibers can still exhibit good fluorescence characteristic after being stretched, bent, washed and rubbed, displaying excellent durability. Different from reported luminescent fibers which required an external power supply or complicated preparation process, the flexible AIEgen fibers fabricated in this study can be prepared continuously in a large-scale way and exhibits effectiveness in clothing display, anti-counterfeiting, information transmission and hazardous gas detection, which shows great application potential for wearable smart textiles.
