Abstract

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.
