Rh2(OAc)4 can catalyze the formation of perfluorophenyl-containing trans-epoxides from the reactions of perfluorophenyl diazomethane with activated aryl aldehydes through sulfur ylide intermediate. In contrast, under the same reaction conditions, trans-alkenes were obtained in excellent yield through tellurium ylide intermediates.
Rh 2(OAc)4可通过全氟苯基重氮甲烷与活化的芳基醛通过硫代叶立德中间体的反应催化含全氟苯基的反式环氧化物的形成。相反,在相同的反应条件下,通过碲化碲中间体以优异的产率获得了反式烯烃。
