Dodecaallylhexasilacyclohexane 4 , which would be a stable precursor for a variety of hexasilacyclohexane derivatives, was synthesized by the reaction of [pedeta · SiH 2 Cl] 2 [Si 6 Cl 12 · 2Cl] ( 1 ) with allylmagnesium bromide. In addition, an effective synthetic route of dodecachlorohexasilacyclohexane 3 from trichlorosilane was found. Deallylmethoxylation of 4 with catalytic amount of iodine and methanol yielded dodecamethoxyhexasilacyclohexane 5 almost quantitatively, but was found to be highly sensitive toward water. Herein, we report the first spectroscopical and structural data of 5 .
