Abstract
Potassium-graphite (C8K) reduces phenyltrichlorosilane to give polyphe nylsilynes in high yields. Branched copolysilanes have been prepared v ia reductive coupling of phenyltrichlorosilane and diorganodichlorosil anes with C8K. Polymers of this type are also obtained by reductive co upling of triflate substituted polysilanes with C8K. The soluble polym ers and copolymers with molecular weights in the range approximate to 4000 to 10000 have been characterized by Si-29-NMR spectroscopy.
