An efficient method for the α-chlorination of ketonesunder basic conditions is described using methyl chlorosulfate. Its applicability for the chlorination of other functional groups has also been studied and it is equally useful for the synthesis of α-chloroesters and amides. Methyl chlorosulfate is described for the first time as a positive chlorine source. Some aldol reactions which occur during

Treatment of a variety of ketones with lithium diisopropylamide followed by p-toluenesulfonylchloride gives α-chloroketones in good yields. In addition, a polymer tosyl chloride reagent has also been shown to effect this transformation.
