Perfluoroalkylmethyl-substituted electrophiliccyclopropane derivatives are readily synthesized in excellent yields by a CrCl3/Fe promoted reaction of perfluoroalkyl iodides with allylmalonate and its analogues in one-pot reaction. Functional groups like ester, cyano and carbonyl are tolerated under such reaction condition.
