Diphenylsilanediol reacts with silyl-bis-triflates and triethylamine under formation of polysiloxanes. A series of new modified organosilicon polymers was prepared by use of special substituted triflate derivatives, obtained by protodesilylation of disilanes, carbosilanes and disilylalkines with CF3SO3H. This simple method allowed the synthesis of compounds in which the siloxane units are connected
