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.
