β-hydroxyalkyl radicals generated by sodium borohydride reduction of oxymercurials react with electron deficient olefins to give addition compounds in an homogeneous process. Heterogeneous reactions are also successful in the presence of catalytic amounts of surfactants and provide a superior method for the “one pot” reductive alkylation of oxymercurials.
由羟基汞的硼氢化钠还原生成的β-烷氧基和β-羟烷基自由基与缺电子的烯烃反应,在均相过程中得到加成化合物。在催化量的表面活性剂的存在下,异相反应也很成功,并为“一锅”氧化汞的还原烷基化提供了一种优越的方法。
