Synthesis of 1,2-Diacylbenzenes from<i>o</i>-Hydroxyaryl Ketone Acylhydrazones Using [(Diacetoxy)iodo]benzene

Abstract

2′-Hydroxyacetophenone and 2′-hydroxypropiophenone acylhydrazones 3 are oxidized to 1,2-diacylbenzenes 4 using [(diacetoxy)-iodo]benzene in dichloromethane at room temperature in a synthetically useful and high yield reaction.
