Abstract
The electroreduction of alkylaryldichlorosilane carried out with Mg cathode and anode in a single compartment cell gave high molecular weight poly(alk ylarylsilane) (M-n = 5200-31000, M-w/M-n = 1.4-1.8) in 5-79% yield. The eff ects of electrode material, monomer concentration, amount of supplied elect ricity, and ultrasound were investigated. This electroreductive method was also successfully applied to the synthesis of polygermanes, silane-geramane copolymers, and also poly[p- (disilanylene)phenylenes].
