SYNTHESIS OF SILICON MONOMERS AND OLIGOMERS CONTAINING CYCLOHEXYLENE RING*
摘要:
1,3-Bis(trichlorosilyl) cyclohexane was obtained by addition of HSiCl3, to cyclohexadiene-1,3in the presence of H2PtCl6.6H2O 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-functional monomer,a cyclic tetramer,while in the case of tetra-functional monomer a cyclic octamer was obtained.These compounds have not been reported in literature.
