Oxidative Ring Opening of 1,3‐Diarylbenzo[<i>c</i>]heterocycles Using <i>m</i>‐CPBA: Preparation of 1,2‐Diaroylbenzenes

Abstract

Abstract An unprecedented oxidative cleavage of benzo[ c ]heterocycles using m ‐CPBA is reported. The reaction of 1,3‐diaryl benzo[ c ]heterocycles with m ‐CPBA ( meta ‐chloroperoxybenzoic acid) at room temperature for 5 min led to the formation of 1,2‐diaroylbenzenes in good to excellent yields.
