Make it strained and fluorinated! A rhodium‐catalyzed domino diazotization/cyclopropenation reaction involving trifluoroethylamine hydrochloride and alkynes has been developed for the synthesis of trifluoromethyl cyclopropenes that can be easily functionalized to afford useful CF3‐containing building blocks for drug discovery.
