The Decomposition of Azibenzil, PhC(N2)COPh, by Catalytic Amounts of Carbanions or of Sodium Borohydride: Evidence for a Hydride-ion Transfer Chain Reaction

Evidence is presented that the conversion of azibenzil, PhC(N2)COPh, into benzil azine induced by catalytic quantities of carbanions or of NaBH4 in Me2SO or MeCN involves a novel hydride-ion transfer chain mechanism.

A Kinetic Study of the Electrochemical Reduction of Azibenzil in Acetonitrile Solution: Evidence for the Transient Formation of a Carbene Anion Radical

Electrode kinetic studies on the reduction of azibenzil PhCOC(N2)Ph in MeCN solution indicate that the reaction follows an ECEh mechanism, the chemical step most propably involving unimolecular loss of N2 from the diazoalkane anion radical with formation of the related carbene anion radical.

Influence of different aryl substitution on the crystal structures of benzil monohydrazone and dibenzil azine parent compounds

A series of benzil monohydrazones (1a, 1d) and corresponding dibenzil azines (2a-2d) featuring different p-aryl substituents have been synthesized and studied in regard of their crystal structures. Configurational and conformational properties as well as non-covalent interaction and packing behaviour of the molecules connected with the different substitution are discussed. The dibenzil azine 2a was found as a polymorph with reference to a known crystal structure.

A convenient synthesis of azines under solvent-free conditions using microwave irradiation

In an extremely fast method the reaction of hydrazine sulfate with a number of aldehydes and ketones, is accelerated by microwave irradiation under solvent free conditions in the presence of CH2CO2Na/CaCl2 to afford high yields of relevant azines.
