    Description / Table of Contents: Synthesis, Characterization, and Reduction of Alkynyl-substituted Chloro-SilanesThe synthesis and characterization of phenylethynyl-silanes of the type (R)(Cl)nSi(C≡C—Ph)3-n (n = 0, 1, 2; R = Ph, H), (R)(R′)(Cl)nSi(C≡C—Ph)2-n (n = 0, 1; R = Me, R′ = H; R = Me, R′ = CH = CH2) und (R)(R′)(R″)Si(C≡C—Ph) (R = Me, R′ = Et, R″ = H) is discussed. The reduction of the phenylethynyl-substituted chlorosilanes with aluminum hydride yields (R)(Ph—C≡C) SiH2 or (R)(H)Si(C≡C—Ph)2 (R = Ph, Me), respectively.The identity of all synthesized compounds is documented by analytical and spectroscopic (IR, MS, 1H-, 13C- and 29Si-NMR) data.
    Notes: Die Synthese und Charakterisierung von Phenylethinyl-Silanen der Form (R)(Cl)nSi(C≡C—Ph)3-n (n = 0, 1, 2; R = Ph, H), (R)(R′)(Cl)nSi(C≡C—Ph)2-n (n = 0, 1; R = Me, R′ = H; R = Me, R′ = CH = CH2) und (R)(R′)(R″)Si(C≡C—Ph) (R = Me, R′ = Et, R″ = H) wird beschrieben. Die Reduktion der Phenylethinyl-substituierten Chlorsilane mit Lithiumaluminiumhydrid führt zu (R)(Ph—C≡C)SiH2 bzw. (R)(H)Si(C≡C—Ph)2 (R = Ph, Me).Die Identität der synthetisierten Verbindungen ist durch analytische und spektroskopische (IR, MS, 1H-, 13C- und 29Si-NMR) Daten dokumentiert.

    Description / Table of Contents: Reaction Ability of Alkynyl-Substituted Chloro-SilanesThe reaction of (Me)(Ph—C≡C)Si(H)(Cl), 1, with different reagents is described: Reduction of 1 with LiAlH4 yields (Me)(Ph—C≡C)SiH2, 2. With H2O (Me)(Ph—C≡C)Si(H)(OH), 3, is obtained; condensation of 3 gives [(Me)(Ph—C≡C)Si(H)]2O, 4. The aminolysis of 1 with N(i(C3H7)2H) yields (Me)(Ph—C≡C)Si(H)[N(iC3H7)2], 5. With Ph2PLi [(Me)(Ph—C≡C)(H)Si]PPh2, 6, is formed and with the Grignard reagents BrMgEt, C≡C—Ph or CH=CH2 the compounds (Me)(Ph—C≡C)Si(H)(Et), 7, (Me)(H)Si(C≡C—Ph)2, 8, or (Me)(Ph—C≡C)Si(H)(CH=CH2), 9, are obtained.All synthesized compounds (2-9) are characterized by analytical as well as spectroscopic (IR, MS, 1H-, 13C- and 29Si-NMR) data.
    Notes: Die Umsetzung von (Me) (Ph—C≡C)Si(H)(Cl), 1, mit verschiedenen Reagenzien wird beschrieben: Reduktion von 1 mit LiAlH4 führt zu (Me) (Ph—C≡C)SiH2, 2. Mit H2O wird (Me)(Ph—C≡C)Si(H)(OH), 3, erhalten; Kondensation von 3 ergibt [(Me)(Ph—C≡C)Si(H)]2O, 4. Durch Aminolyse von 1 mit N(i(C3H7)2H) wird (Me)(Ph—C≡C)Si(H)[N(iC3H7)2], 5, gebildet. Mit Ph2PLi wird [(Me)(Ph—C≡C)(H)Si]PPh2, 6, erhalten und die Grignard-Reagenzien BrMgEt, C≡C—Ph bzw. CH=CH2 ergeben die Verbindungen (Me)(Ph—C≡C)Si(H)(Et), 7, (Me)(H)Si(C≡C—Ph)2, 8, bzw. (Me)(Ph—C≡C)Si(H)(CH=CH2), 9.Alle dargestellten Verbindungen (2—9) wurden elementaranalytisch und spektroskopisch (IR, MS, 1H-, 13C- und 29Si-NMR) nachgewiesen.
