reaction and the amino-to-triflate transformation, functionalized tri-, tetra-, penta- and hexasilanes have been synthesized. α,ω-Triflate substituted oligosilanes containing π-systems have also been obtained. These compounds are useful building blocks for new organosilicon polymers. The formation of the silicon polymers at low temperatures, in short reaction times, and with high yields is reported.

The selective cleavage of phenylsilanes by triflic acid gives novel silyltriflates. Unique, substituted derivatives have been synthesized by alkylation with organometallic reagents. Triflate derivatives of oligo- and cyclo-silanes are similarly formed.
