| Popis: | Chlorotrimethylgermane 1 and dichlorodimethylgermane 4 react with trichlorosilane and triethylamine to provide trichlorosilylgermanes Me4−nGe(SiCl3)n (n=1: 2; n=2: 5) in fair yields, as distillable liquids. The formation of 2 is followed by base-catalysed decomposition reactions leading to novel solid (Me3Ge)2Si(SiCl3)2 3. Chlorotrialkylstannanes 6a–c (6a: R=CH3, 6b: R=C2H5, 6c: R=n-C4H9) react with trichlorosilane and triethylamine providing the branched silylstannanes (R3Sn)2Si(SiCl3)2 7a–c and traces of silylstannanes R3SnSiCl3 8a–c. Only 7a was isolated in a pure state. Heating 7a or crude 7b and 7c with benzyl chloride leads to the formation of benzyltrichlorosilane (10). The constitution of compounds 2, 3, 5 and 7a was confirmed by MS, NMR and analytical data. The structures of C6D6-solvated 3 and C6H6-solvated 7a were determined by X-ray diffraction, and shown to be isotypic. |
