Usage

General Description

Benzophenone azine, also known as diphenylketene imine, is an organic compound that belongs to the family of azine compounds. It is a yellow to orange solid that is insoluble in water but soluble in organic solvents. Benzophenone azine is commonly used as a photochemical initiator in the synthesis of polymers and in photolithography processes. It is also utilized in the production of dyes, pigments, and pharmaceuticals. Additionally, benzophenone azine has been studied for its potential use as a reagent in organic chemistry and as a photostabilizer in plastics and coatings. However, it is important to note that benzophenone azine can be hazardous, and proper safety measures should be taken when handling and storing this chemical.

Formation of Osmium Alkylidene, Alkylidyne, and Dinitrogen Complexes from Reactions of OsCl2(PPh3)3with Diazoalkanes

The reactions of OsCl2(PPh3)3 with a series of diazoalkanes were investigated. The reactions with monosubstituted diazoalkanes N2CHR gave the desired osmium alkylidene complexes OsCl2(=CHR)(PPh3)2, the stability of which is dependent on the substituent on the alkylidene carbons. The five-coordinate osmium alkylidene complex OsCl2(=CHCOOMe)(PPh3)2 is thermally stable, whereas the analogous complex OsCl2(=CH-p-tol)(PPh3)2 readily rearranges to its hydrido-alkylidyne form OsHCl2(C-p-tol)(PPh3)2. A substitution reaction of OsCl2(=CHCOOMe)(PPh3)2 with PCy3 produced the hydrido-alkylidyne complex OsHCl2(CCOOMe)(PCy3)2, revealing the effect of the phosphine on the relative stability of OsCl2(=CHCOOMe)(PR3)2 and OsHCl2(CCOOMe)(PR3)2. The reaction of OsCl2(PPh3)3 with the acceptor-acceptor disubstituted diazoalkane dibenzoyl diazomethane, bearing COPh substituents, led to the formation of the metallacyclic complex OsCl2{κ2-N,O-[N2C(COPh)C(Ph)O]}(PPh3)2 due to the chelating effect of dibenzoyl diazomethane. The complex OsCl2(PPh3)3 catalyzed the homocoupling of the diazoalkane N2CPh2 to give the azine Ph2C=N-N=CPh2. The η1-N2 coordinated binuclear complex (Ph3P)2ClOs(μ-Cl)3Os(PPh3)2(N2) was isolated as a minor product, which was considered to be an off-cycle product in the catalytic reaction.

HKUST-1 derived Cu?CuO: X /carbon catalyst for base-free aerobic oxidative coupling of benzophenone imine: High catalytic efficiency and excellent regeneration performance

The oxidative coupling of imines to ketazine with molecular oxygen is a green process towards the synthesis of hydrazine or hydrazine hydrate, which could efficiently address the economic and environmental issues of the traditional Raschig or peroxide-ketazine process. Herein, we developed an efficient heterogeneous base-free benzophenone imine oxidative coupling route with O2 catalyzed by Cu/CuOx/carbon materials derived from MOFs under mild conditions. Under optimized conditions, the conversion of BI is up to 98.2% and the selectivity of ketamine is 94.9%. This catalyst has excellent structure stability, recycling, and regeneration performance, owing to the carbonization of organic ligands of MOF at high temperature. More importantly, it is confirmed that the metallic Cu core is essential to improve the catalytic performance of the CuO shell in the BI oxidative coupling reaction, due to the promotion of electron transfer in the CuO surface, making dissolved O2 molecules more easily insert oxygen vacancies. This strategy might open an avenue to the sustainable catalytic synthesis of hydrazine or hydrazine hydrate. This journal is
