HCID 11121822Dimethylsilanediyl bis(trifluoromethanesulfonate)Yield 60.1%

Procedure

An oven-dried 100 mL-RB flask is charged with dichlorodimethylsilane (6.45 g, 0.05 mol). Then trifluoromethanesulfonic acid (15 g, 0.10 mol) is added dropwise. The mixture is heated at 60° C. until no HCl evolves. The residue is distilled to yield 10.7 g (60%) of the product as a clear liquid. 1H NMR (500 MHz, CDCl3, in ppm) δ 0.88 (s, 6H).
