The reactions of benzylsulfonyl halides with phenyllithium have been studied. The reaction of benzylsulfonyl chloride with phenyllithium in diethyl ether at 20–25° gave lithiumbenzyl sulfinate as a main product, in addition to other eight products. While the reaction of benzylsulfonyl fluoride with phenyllithium under a similar condition afforded a disulfone, α- benzylsulfonyl-α-benzenesulfonyltoluene, as a major product. On the other hand, the ...
