SYNTHESIS OF ORGANOSILICON POLYMERS FROM SPECIALLY SUBSTITUTED SILYLTRIFLATE DERIVATIVES

Diphenylsilanediol reacts with silyl-bis-triflates and triethylamine u nder formation of polysiloxanes. A series of new modified organosilico n polymers was prepared by use of special substituted triflate derivat ives, obtained by protodesilylation of disilanes, carbosilanes and dis ilylalkines with CF3SO3H. This simple method allowed the synthesis of compounds in which the siloxane units are connected by disilane, carbo silane or silylalkine bridges. The polymeres are characterized by NMR- spectroscopy (Si-29, C-13, H-1).
