A mild exchange reaction of xanthates with bromine

Abstract : Secondary S-alkyl-O-ethyl (or O-neopentyl) xanthates can be converted into the corresponding bromides by heating with ethyl 2-bromo-2-methylpropionate and cumyl peroxide in refluxing chlorobenzene; this transformation can be coupled to a xanthate transfer radical addition to an olefin.
