硅氯仿和环己二烯-1,3进行硅氢加成反应,生成1,3-双(三氯硅基)环己烷,经醇解制得1,3-双(三乙氧硅基)环己烷,与溴化甲基镁反应,制得1,3-双(二乙氧甲硅基)环己环、1-(乙氧二甲硅基)-3-(二乙氧甲硅基)环己烷和1,3-双(乙氧二甲硅基)环己烷,它们在盐酸溶液中分别进行水解,得到各种含次环己基的有机硅低聚体,其中2,2,4,4,11,11,13,13-八甲基-3,12-二氧(杂)-2,4,11,13-四硅(杂)三环[11,3,1,1~(5,9)]十八烷和D_4相似,可能经开环聚合得到聚硅次环己基硅氧烷。 相似文献

1,3-Bis(trichlorosilyl) cyclohexane was obtained by addition of HSiCl_3, to cyclohexadiene-1,3in the presence of H_2PtCl_6.6H_2O in isopropyl alcohol. The new compound was ethanolysed andmethylated to form di-methyl tetra-ethoxy disilyl, tri-methyl tri-ethoxy disilyl and terta-methyldi-ethoxy disilyl cyclohexanes. These di-to tetra-functional monomers were hydrolyzed by hydrochloric acid in ether. The di-functional monomer yielded cyclic dimer similar to octamethylcyclotetrasiloxane and the tri-functionalmonomer, a cyclic tetramer, while in the case of tetra-functional monomer a cyclic octamer wasobtained. These compounds have not been reported in literature. 相似文献
