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
