Reaction of various electron‐deficientalkenes, as well as functionalized styrene derivatives with CF3SiMe3−NaI system is studied. Relative reactivity of the substrates is established. It is shown that many α,β‐unsaturated esters can be difluorocyclopropanated efficiently under “slow addition protocol” conditions, which provides access to mono‐ and spirocyclic gem‐difluorocyclopropyl‐substituted carboxylic

TFDA is readily prepared from the reaction of fluorosulfonyldifluoroacetic acid with trimethylsilyl chloride, and it is a very effective and efficient source of difluorocarbene for use in addition reactions to alkenes of a broad scope of reactivities. Acid-sensitive substrates may require an additional purification step involving treatment of the distilled TFDA with sufficient Et3N to remove the acid
