Bis(trifluoromethylsulfonyloxy)organosilicon Compounds as Synthetic Materials for New Silicon Polymers The new polycarbosilanes, polysiloxanes, and polysilylenealkynes 1c–6c were obtained by condensation of electrophilic α,ω‐bis(trifluoromethylsulfonyloxy)organosilicon compounds 1b–6b with nucleophiles such as organolithium and organomagnesium compounds. The required silyl triflate derivatives 1b–6b have been prepared by reaction of the corresponding amino‐, allyl‐, or phenylsilanes 1a–6a with trifluoromethanesulfonic acid.
