Procedure

88.54 g (0.200 mol) of di(pentafluorophenyl)chloroethoxysilane in Et2O is slowly added to solution of C6F5—Li (0.200 mol, 34.80 g, prepared in situ) in Et2O at −78° C. The solution is stirred for over night allowing it to warm up to room temperature. Formed clear solution is filtered and evaporated to dryness to result tri(pentafluorophenyl)ethoxysilane, (C6F5)3SiOEt.
