(Trifluoromethyl)trimethylsilane (Me3SiCF3) was converted to (trifluoromethyl)tributyltin (Bu3SnCF3, 1) in quantitative yield by treatment with bis(tributyltin) oxide in tetrahydrofuran under fluoride ion initiation. Bu3SnCF3 was found to readily trifluoromethylate disilyl sulfides at room temperature giving the corresponding trifluoromethylated di- and trialkylsilanes in high yields. This method provides a new approach for the preparation of silicon-based trifluoromethylating reagents via transtrifluoromethylation of compounds containing Si-S bonds.
