Abstract
Treatment of LiC(SiMe2H)(3)]. 2THF (1) with alkenylchlorosilanes produced s terically 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(SiMe 2H)(2). Pt or Rh catalyzed intramolecular hydrosilylation of H2C=CHSiMe2C(S iMe2H)(3) (4) occurred to pro duce a new 1,3-disilacyclobutane derivative 1 5. Intermolecular hydrosilylation was favored for 5, 8, and 10, producing o ligomeric products. (C) 2001 Elsevier Science B.V. All rights reserved.
