Abstract

Arenesulfonyl chlorides react with vinylarenes in the presence of dichlorotris (triphenylphosphine) ruthenium (II) catalyst and 1 molar equiv of a tertiary amine to form a,@- unsaturated sulfones 2. Only the E isomers of the sulfones are formed. In reactions of arenesulfonyl chlorides containing an electron-withdrawing C1 or NOP substituent with a- methylstyrenes, 2-aryl-3-(arylsulfonyl) propenes (5) are also formed. Mechanisms for ...
