摘要：

Norbornene reacts with trichlorosilane to generate norbornyltrichlorosilane in high yield. The slow hydrolysis of norbornyltrichlorosilane in acetone yields incompletely condensed norbornylsilasesquioxanes. The compound C42H70O11Si6 can be isolated from this reaction. On the basis of elemental analyses, H-1, C-13 and Si-29 NMR, mass spectroscopy, infrared spectroscopy, and crystallographic analysis, C42H70O11Si6 is formulated as [(C7H11)6Si6O7(OH)4], with the Si6O7 framework being composed of two perpendicular Si4O4 planes sharing an edge. [(C7H11)6Si6O7(OH)4] is a putative model of vicinal [Si(OH)]2 sites on the surface of partially dehydroxylated silica.
