Alkenesulfonyl chlorides reacted with vinylarenes in the presence of a catalytic amount of dichlorotris(triphenylphosphine)ruthenium(II) to give substituted 1:1 adducts, which were dehydrochlorinated and desulfonylated successively to form substituted (E,E)-1,3-dienes in good yield.
在催化量的二氯三(三苯基膦)钌 (II) 存在下,烯磺酰氯与乙烯基芳烃反应生成取代的 1:1 加合物,这些加合物依次脱氯化氢和脱磺酰化生成取代的 (E,E)-1,3-二烯良好的产量。
