Synthesis of new kinds of silicon-containing monomers

Summary

• 1. In presence of H₂PtCl₆ addition of alkyldichlorosilanes to CH≡CH, CH₂=CH₂, and CH₂=CHCH₃ proceeds in almost quantitative yield at 20–60°.

• 2. In presence of platinum catalysts alkyldichlorosilanes give the higher yields of addition products, whereas in presence of peroxides, trichlorosilane gives the higher yields.

• 3. By the condensation of alkyldichlorosilanes and trichlorosilane with aryl and alkenyl halides at 600°, previously inaccessible di- and tri-chlorosilanes were prepared.

• 4. Silicon-containing derivatives of butadiene, acrylic acids, and vinyl ethers and acetals were synthesized for the first time; these compounds give solid linear polymers at atmospheric pressure.
