Acyl hydrazides are widely found in bioactive compounds and have important applications as versatile synthetic intermediates. In the current report, a photoredox-catalyzed hydroacylation of azobenzenes was disclosed with carboxylic acids acylation reagent, affording variety N,N′-disubstituted hydrazides. The process possesses advantages mild reaction conditions, broad substrate scope, high efficiency. Preliminary mechanistic investigation indicated that addition an acyl radical to azo compound should be involved.
