- 論文の詳細を見る
Various 2,2,2-trifluoroethyl onium triflates were synthesized by treating tertiary amines, pyridines, quinoline, a triazole, sulfides, and a phosphine with (2,2,2-trifluoroethyl)phenyliodonium triflate. Sulfoxides and N-oxide were converted to the corresponding trifluoroethylated salts. As an application, CsF-treatment of (2,2,2-trifluoethyl)triphenylphosphonium triflate with an aldehyde was shown to produce a trifluoromethylated olefin.
