Abstract

Treatment of LiC(SiMe₂H)₃]·2THF (1) with alkenylchlorosilanes produced sterically hindered alkenylsilanes (4-10) of structure H₂C=CH-(CH₂)_n SiRR′C(SiMe₂H)₃ (R = Me; R′ = Me or Cl; n = 0, 1, or 4). The Peterson reaction of 1 with carbonyl compounds gave sterically hindered olefins R(R′)C=C(SiMe₂H)₂. Pt or Rh catalyzed intramolecular hydrosilylation of H₂C=CHSiMe₂C(SiMe₂H)₃ (4) occurred to produce a new 1,3-disilacyclobutane derivative 15. Intermolecular hydro silylation was favored for 5, 8, and 10, producing oligomeric products.
