gives highly regio- and stereoselectively (E)-α-stannylvinyl sulfones 2 in high yields. (E)-α-Stannylvinyl sulfones 2 are new difunctional group reagents which undergo Stillecoupling reactions with acyl chlorides 3 to afford stereoselectively (Z)-α-arylsulfonyl-α,β-unsaturatedketones 4 in good yields. A one-pot stereoselectivesynthesis of (Z)-α-arylsulfonyl-α,β-unsaturatedketones 4 has also been achieved
