Abstract
Network polysilanes with various substituents have been prepared by a disproportionation reaction of 1,1,2,2-tetraethoxy-1,2-dimethyldisilan e with a small amount of organolithium reagents. Aromatic dilithio com pounds lead to incorporation of aromatic bridges into the network poly silanes, which show relatively higher electroconductivity by iodine do ping. It seems that lithium ethoxide catalyzes the polymerization.
