J. Clayden et M. Julia, ALLYLIC SULFONES AS ALLYL ANION EQUIVALENTS - HOMOALLYLIC ALCOHOLS FROM METAL-CATALYZED REACTIONS OF SULFONES WITH ALDEHYDES AND KETONES, Journal of the Chemical Society, Chemical Communications, (16), 1994, pp. 1905-1906
Reduction of allylic sulfones with diethylzinc, catalysed by palladium
(0), gives nucleophilic organometallic species, which react in situ wi
th carbonyl compounds to give homoallylic alcohols in high yield.
