Reaction Conditions

Reaction Steps

A dry 3-neck round bottom flask with nitrogen and stir-bar is charged with approximately (9.5 mL, 14.5 g at −78° C., 0.12 mol) iodotrifluoroethylene and 200 mL diethylether pre-cooled to −78° C. Sec-butyl lithium (89 mL, 1.4 M solution, 0.12 mol) is added dropwise over 1 hour. Solution is allowed to stir for 5 minutes at −78° C. Chlorotriethoxysilane (24.35 mL, 0.12 mol) is added over 5 minutes at −78° C. The solution is allowed to warm slowly and allowed to stir overnight. A clear yellow solution remains. Fractional distillation is used to purify the product.
