Alkyl and acyl xanthates are useful precursors of alkyl and acyl radicals. With acyl xanthates, the radical chain process can be initiated by visible light, and capture of the intermediate acyl radical leads to various carbonyl derivatives. In some cases, the acyl radical extrudes carbon monoxide to give an alkyl radical which in turn can be trapped by an electrophilic olefin. Alkyl xanthates in contrast require U.V. lighting but the reaction sequence can sometimes be initiated with visible light if small amounts of S-benzoyl-O-ethyl xanthate are incorporated into the medium.
