volatility, storage instability, toxicity, and explosiveness. We report the application of trifluoroacetaldehyde N-tosylhydrazone as a CF3CHN2 precursor capable of generating in situ trifluorodiazoethane under mild basic conditions. Copper-catalyzed P–H, O–H, S–H, and C–H insertion reactions of trifluoroacetaldehyde N-tosylhydrazone revealed its wide applicability in the synthesis of trifluoroethyl-containing
