Abstract

The hydrosilylation reactions of allylgermanes R3GeAll (R3 = Cl3, Me3) in the presence of a platinum catalyst (Karstedt catalyst) with methylchlorohydridesilanes MenCl3–nSiH (n = 0–2) and 1,1,3,3-tetramethyldisiloxane have been studied. It was found that only 1,3-adducts are formed. In some cases, the replacement of only one methyl group at silicon with Cl (or vice versa, Cl for methyl group) leads not only to a decrease in the yields of the products obtained, but to a complete absence of reaction. A possible route of the studied reactions is proposed. The identification of the synthesized compounds was carried out using the methods of gas-liquid chromatography, 1H NMR spectroscopy and chromatography-mass spectrometry.
