## Abstract Potassium (trifluoromethyl)trimethoxyborate is introduced as a new source of CF~3~ nucleophiles in copper‐catalyzed trifluoromethylation reactions. The crystalline salt is stable on storage, easy to handle, and can be obtained in near‐quantitative yields simply by mixing B(OMe)~3~, CF~3
