二甲基二氯硅烷和甲基三氯硅烷与钠-钾合金在萘存在下在四氢呋喃中反应，得到双环和笼状聚硅烷Si 8 Me 14、Si 5 Me 16、Si 10 Me 18、Si 10 Me 18、Si 11 Me 18和Si 13 Me 22。Si 8 Me 14在环己烷中的光解产生Si 7 Me 12。这些化合物的结构证据。通过ESR光谱研究了几种聚环聚硅烷还原形成的阴离子自由基。
Dimethyldichlorosilane and methyltrichlorosilane react with sodium-potassium alloy in the presence of naphthalene in tetrahydrofuran to yield bicyclic and cage polysilanes, Si8Me14, Si5Mei6, Si10Meis, Sil0Me, 8, SiuMei8, and Sii3Me22. The photolysis of Si8Mei4 in cyclohexane yields Si7Mei2. Structural evidence for these compounds is presented. Anion radicals formed by reduction of several of the polycyclopolysilanes were studied by esr spectroscopy.
