Sulfonylchlorides were reduced to anhydrous sulfinate salts with magnesium under sonication. These sulfinates were alkylated to sulfones with alkyl chlorides in the presence of catalytic sodium iodide under sonication. A variety of aliphatic sulfones was efficiently prepared by this one-pot two-step procedure.

chemoselectivity for monobromination. Selective oxidation of sulfides to sulfoxides and sulfones has also been studied and good to excellent yields of the desired products were obtained. Acetic acid was found to be the solvent of choice for these reactions. This simple method represents an ecologically benign and alternative pathway for the oxidative halogenation of anilines and the oxidation of sulfides to

Methylbenzylsulfone (m.p. 128°) and benzyl-ω-styrylsulfone (m.p. 145°) were obtained in several ways from benzylsulfonylacetic acid and benzaldehyde. The ethylester of benzylsulfonylacetic acid and benzaldehyde gave the ethylester of α-benzylsulfonylcinnamic acid. 3-Benzylsulfonylcoumarin (m.p. 175°) was obtained from benzylsulfonylacetic acid and salicylaldehyde. The NMR-dates of methylbenzylsulfone
