1-Iodoalkyl sulfones are prepared by conversion of alkyl sulfones into 1-sulfonylalkyltriethylalanates by reaction with butyllithium and triethylalane and subsequent reaction with iodine. The same method can be applied to the conversion of methyldiarylphosphine oxides into iodomethyldiarylphosphine oxides and of S-methylsulfoximines into S-iodomethylsulfoximines.
