are readily oxygenated in the presence of a five-coordinate cobalt(II)-Schiffbasecomplex, Co(II)(MeOSalen) (Py) leading to quantitative formation of novel 1-(-nitrophenylazo)-1-peroxy Co(III) complexes 2, which were isolated as crystals. A plausible mechanism involving hydrogen abstraction by Co(III)(O2−.) from the substrate followed by formation of a substrate anion Co(III) complex intermediate

An efficient and novel method using palladium catalyst for the synthesis of benzo[d][1,2]diazepines by [5 + 2] annulation of N-arylhydrazones with alkynes has been developed. This methodology undergoes through eight membered palladacycle serving as a backbone for the formation of C-C/C-N bond to provide benzodiazepine derivatives in moderate to good yield.
