Abstract
The 1,3,5-trisilacyclohexane skeleton [CH2Si(Ph)(C2H)](3) equipped with three ethynyl groups was synthesised and functionalised to afford tridentate Lewis acids with directed functions. Hydroboration with HB(C6F5)(2) yielded the ethenylborane {CH2Si(Ph)[C2H2B(C6F5)(2)]}(3), while metalation with gallium organyls afforded {CH2Si(Ph)[C2Ga(R)(2)]}(3) (R = Me, Et). The new compounds were identified by elemental analyses, multi-nuclear NMR spectroscopy and IR spectroscopy. Crystal structures were obtained for all-cis-[CH2Si(Ph)(OMe)](3), cis-trans-[CH2Si(Ph)(Cl)](3), all-cis-[CH2Si(Ph)(H)](3) and all-cis-[CH2Si(Ph)(C2H)](3).
