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].
在单个隔室中用Mg阴极和阳极对烷基芳基二氯硅烷进行电还原,得到5中的高分子量聚(烷基芳基硅烷)(M(n)= 5200-31000,M(w)/ M(n)= 1.4-1.8) -79%的产率。研究了电极材料,单体浓度,供电量和超声的影响。这种电还原方法也已成功地用于合成聚锗烷,硅烷-天竺葵共聚物以及聚[对-(二亚二甲苯基)亚苯基]。
