A regiodivergent chlorine‐atom‐transfer reaction involving the ring‐opening of trichloromethylcyclopropanes was developed. Treatment of a trichloromethylcyclopropane with ZnMe2provided the β‐chloro‐α‐dichlorovinyl ester with high stereoselectivity through a chloride‐anion‐mediated atom‐transfer ring‐opening reaction. In contrast, the use of CuCl afforded the α‐chloro‐β‐dichlorovinyl ester by a chlorine‐radical‐mediated atom‐transfer ring‐opening reaction.
