A novel and highly effective halogenation of alkanes with halides on oxidation with m-Chloroperbenzoic acid: Looks old, but new reaction

Article abstract of DOI:10.1246/cl.1998.1085

The combination of tetraalkylammonium halides (Cl^-. Br^-) and m-chloroperbenzoic acid in CH₃CN effectively halogenated alkanes accompanied by the formation of alkyl m-chlorobenzoate; for which the alkyl halides were formed via a non-photoinduced radical mechanism and the esters were derived from a non-radical process and concomitant with the formation of corresponding trialkylamine.
