烷基芳基二氯硅烷在单室电解槽中用镁阴、阳极电还原，以5-79%的产率得到高相对分子质量的聚烷基芳基硅烷(M-n=5 2 0 0~31000，M-w/M-n=1.4~1.8)。考察了电极材料、单体浓度、供电电量、超声波等因素对电极性能的影响。这种电还原方法还成功地应用于多聚锗、硅烷-锗共聚物的合成，以及聚[对二硅苯基]的合成。
The electroreduction of alkylaryldichlorosilane carried out with Mg cathode and anode in a single compartment cell gave high molecular weight poly(alkylarylsilane) (M-n = 5200-31000, M-w/M-n = 1.4-1.8) in 5-79% yield. The effects of electrode material, monomer concentration, amount of supplied electricity, 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].
