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

The combination of tetraalkylammonium halides (Cl-, Br-) and m-chloroperben zoic acid in CH3CN effectively halogenated alkanes accompanied by the forma tion of alkyl In-chlorobenzoate; for which the alkyl halides were formed vi a a non-photoinduced radical mechanism and the esters were derived from a n on-radical process and concomitant with the formation of corresponding tria lkylamine.
