Reduction of α-bromosulfones 1, 5, 13-16 by cat.(PhSe)2/NaBH4 occurred site-selectively in high yields. This reduction of 1,3- or 1,4-dibromobis(sulfone) 21 and 25 was applied to intramolecular coupling reactions to give the three- and four-membered carbocycles 26-28.

Treatment of dibromomethyl phenyl sulfone with zinc powder in the presence of a catalytic amount of lead in THF afforded phenylsulfonyl-substituted dizinciomethane. The species converts a ketone or aldehyde into an alkenyl sulfone via a Wittig-type olefination reaction with the assistance of β-TiCl3. Copyright
Halogens in γ-position enhance the acidity of alkyl aryl sulfones and alkane nitriles

On the basis of measuring the rates of base-catalyzed deuterium exchange the pKa values of a series of 3-halopropyl aryl sulfones and 4-halobutyronitriles were estimated. It was shown that halogen substituents, although separated from the carba
