CONVENIENT APPROACH TO NOVEL ORGANOSILICON POLYMERS

Reactions of ga-bis[[(trifluoromethyl)sulfonyl]oxy]-substituted organo silicon compounds with organic dilithio reagents (or the corresponding di-Grignard compounds) lead to the formation of new organosilicon pol ymers, which show a regular alternating arrangement of silylene or dis ilylene groups and ethynylene, diethynylene, or phenylene units in the polymer backbone. Conversions of the silyl triflates with hydroquinon e or diphenylsilanediol afford various structured polysiloxanes. The r equired silyl triflates are prepared by protodesilylation of the corre sponding phenyl- or aminosilanes with triflic acid.
