HCID 4457970Diisopropylsilyl bis(trifluoromethanesulfonate)Yield 60%

Procedure

An oven-dried 100 mL-RB flask is charged with dichlorodiisopropylsilane (9.2 g, 0.05 mol). Then 15 g of trifluoromethanesulfonic acid (15 g, 0.10 mol) is added dropwise. The mixture is heated at 60° C. until no further HCl evolves. The residue is distilled to yield 12 g (60%) of the product as clear liquid. 1H NMR (500 MHz, CDCl3, in ppm) δ 1.58 (heptet, 2H, J=7.2 Hz), 1.24 (d, 12H, J=7.2 Hz).
