Metal-free Oxidations with m-CPBA: An Octennial Update

Abstract

Abstract: meta-Chloroperbenzoic acid (mCPBA) is a readily available peroxide that is a powerful oxidizing agent utilized in a range of oxidative reactions. Metal-free oxidations mediated by mCPBA involving selective oxidation of aliphatic amines to oximes, selective oxidation of organosulphides/ aldehydes, synthesis of heterocyclic N-oxides, domino C[sp2] hydroxylation/ annulation of enaminones (heterocyclic ring formation), acid to phenol conversion, oxidation of exocyclic C=C bond, oxidative ring contraction, etc. have been comprehensively and critically examined in this mini-review from 2015 to date.
