Procedure

30.80 g (0.155 mol) ClSi(OEt)3 in Et2O is slowly added to solution of CF2═CF—Li (0.155 mol 13.633 g, prepared in situ) in Et2O at −78° C. Reaction mixture is stirred overnight while it will slowly warm to room temperature. LiCl is removed by filtration and the product, trifluorovinyltriethoxysilane, is isolated by distillation.
