Synergistic photocatalysis enables aerobic oxo-hydrazination of α-diazoacetates with azobenzenes

A photocatalytic oxo-hydrazination of α-diazoacetates with azobenzenes has been developed. With air as oxygen source, the reaction proceeded smoothly and afforded previously unknown N , N '-diarylhydrazino-containing oxoacetates. Mechanistically, the reaction is enabled...
