Abstract

Abstract: 1,3-Bis (trichlorosilyl) cyclohexane (Ⅰ) was synthesized by the addition of HSiCl₃ to cyclohexadiene-1,3 in the presence of H₂PtCl₆·6H₂0 in isopropyl alcohol. (Ⅰ) was ethanolysed to form 1,3-bis(triethoxysilyl) cyclohexane (Ⅱ) which was methylated and then hydrolyzed to form dimer, namely 2,2,4,4,11,13,13,-octamethyl-3,12-dioxy-2, 4,11, 13-tetrasilicon tricyclo-[11, 3,1,1^5,9] octadecane similar to octamethylcyclo-tetrasiloxane. The structure of these new silicon monomer and dimer were determined by ¹H-NMR, ¹³C-NMR and ²⁹Si-NMR.

Key words: Silicon, NMR
