Gs. Lyashenko et al., 3-PHENOXY-1-PROPYNYL AND 3-PHENYLTHIO-1-PROPYNYL SUBSTITUTED DERIVATIVES OF SILICON AND GERMANIUM, Russian chemical bulletin, 43(3), 1994, pp. 471-473
Reactions of bromomagnesiopropargyl phenyl ethers and their isostructu
ral sulfides BrMgC=CCH(2)XPh (X = O, S) with MeVinSiCl(2), Me(CH2Cl)Si
Cl2, EtSiHCl(2), and Me(2)SiHCl afforded the corresponding 3-phenoxy-
and 3-phenylthio-1-propynyl substituted derivatives of silicon (PhXCH(
2)C=C)(2)SiRR(1) and PhXCH(2)C=CSiHMe(2) (X = O, S). Reactions of the
above-mentioned Iotsitch reagents with GeCl4 led to the corresponding
germanium derivatives (PhXCH(2)C=C)(4)Ge (X = O, S).
