Copper-Catalyzed Divergent1,4-Polyhaloalkylcyanationof 1,3-Enynes

Abstract We report a switchable copper-catalyzed divergent 1,4-polyhaloalkylcyanation of 1,3-enynes to construct a series of polyhalogenated allenes with high chemoselectivity and regioselectivity. The 1,4-dichloromethylcyanation of 1,3-enynes is realized by merging aminoalkyl ra...
