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.
