In conjunction with sodium borohydride as stoichiometric reagent a catalytic quantity of bis(4-perfluorohexylphenyl) diselenide converts vicinal dimesylates to the corresponding alkenes in good yield on warming in ethanol. The diselenide is recovered in high yield by continuous fluorous extraction.
与作为化学计量试剂的硼氢化钠一起,催化量的双(4-全氟己基苯基)二硒化物在乙醇中升温时,可以将邻位二甲基化产物以良好的产率转化为相应的烯烃。通过连续的氟萃取以高收率回收二硒化物。
