Abstract: | 1, 1, 3, 3, 5, 5‐Hexavinyl‐1, 3, 5‐trisilacylohexane Si(CH=CH2)2CH2]3 was synthesized and hydrosilylated with trichlorosilane to afford the first generation of a dendrimer. Conversion of this molecule with 18 Si–Cl functions on its surface with an excess of vinylmagnesium bromide yielded the 18‐fold vinylated dendrimer. The new compounds were identified by elemental analyses, multi‐nuclear NMR spectroscopy, and mass spectrometry. Crystal structures were obtained for Si(CH=CH2)2CH2]3 and Si(CH2–CH2SiCl3)2CH2]3. |
