An efficient and operationally simple synthesis of <i>gem</i>-bromofluorocyclopropanes under mild conditions has been developed. The method employs ethyl dibromofluoroacetate (EDBFA) as an accessible and inexpensive source of the bromofluorocarbene (:CFBr) intermediate. The protocol provides the bromofluorocyclopropane products in excellent yields, including examples synthesized in multigram scales. The chlorinated ester, ethyl dichlorofluoroacetate (EDCFA), is also utilized to make the analogous <i>gem</i>-chlorofluorocyclopropanes.
