The title reaction in the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium(0) affords alkylative coupling products in good to excellent yields in 1,2-dichloroethane at room temperature. This coupling reaction under C(sp2)–O cleavage proceeds stereospecifically. The reaction does not affect a coexisting vinyl sulfide group. This feature enables 1,2- and 1,3-carbonyl transposition
在催化量的四(三苯基膦)钯(0)存在下的标题反应在室温下在1,2-二氯乙烷中以良好至极好的产率提供烷基化偶联产物。这种在 C(sp2)-O 裂解下的偶联反应立体特异性地进行。该反应不影响共存的乙烯基硫醚基团。此功能可通过苯硫基取代的烯醇磷酸酯在有或没有烷基化的情况下实现 1,2- 和 1,3- 羰基转座。
