Hypervalent Iodine Oxidation of Acid Hydrazides: A New Synthesis of<i>N,N</i>′-Diacylhydrazines

Abstract

Abstract Hypervalent iodine oxidation of p-substituted benzohydrazides (1a-h), phenylacetohydrazide (1i) and heterocyclic acid hydrazides (1j-I) using one equivalent of iodobenzene diacetate in dry dichloromethane or acetonitrile leads to dimerization thereby providing a new and facile method for the synthesis of N,N-diacylhydrazines 2.
