The addition of tetrachloromethane to trifiuoroethene catalyzed by copper complexes gives 1:1 adducts in up to 97% yield under mild reaction conditions. The catalytic activity and the regioselectivity of copper, ruthenium and palladium complexes and dibenzoyl peroxide have been compared. Differences in regioselectivity indicate that the copper-coordinated trichloromethyl radical is involved in copper-assisted
在温和的反应条件下,通过铜络合物将四氯甲烷添加到三氟乙烯中可得到1:1的加合物,收率高达97%。比较了铜,钌和钯配合物以及过氧化二苯甲酰的催化活性和区域选择性。区域选择性的差异表明铜配位的三氯甲基自由基参与铜辅助的加成反应,而未络合形式的自由基物种在其他情况下也起作用。
