✦ Synopsis

Phenylsulfonylmercuration of 1,3-dienes gives mercury adducts, which on treatment with base afford phenylsulfonyldienes. In most cases the reaction proceeds regioselectively to give 2-(phenylsulfonyl)-1,3-dienes. These are useful synthetic intermediates and can be readily transformed to a variety of functionalized allylsulfones by Michael-type addition.

The palladium(II)-catalyzed chloroacetoxylation of 1,3-dienes is employed to prepare 1-chloro-4-acetoxy-2-alkenes which are then transformed into 1-phosphoryl-or lsulfonyl-4-acetoxy-2-alkenes respectively. Elimination of acetate is promoted by palladium(O)-catalysis or by sodium hydride, producing t
