摘要：

Synthesis and properties of (4-CH3-C6H4)3SiSiH3, (C6H5)2HSiSiH2C6H5, C6H5Cl2SiSiH3, (C6H5)2ClSiSiH3, (H3SiSiH2)2Se, H3SiSiH2ESiH3, H2Si-Si(H2)-E (E = S, Se), as well as [GRAPHICS] characterisation by IR-, MS-, NMR-spectroscopy are described. Reactions of phenylsubstituted disilanes with HCl in the presence of catalytic amounts of AlCl3 provide chorinated chlorophenylsubstituted disilanes. Condensation of these chlorodisilanes with disilathiane or disilaselenane yield cyclic and acyclic silachalkogenanes containing disilanyl units. The structure of (C6H5)3SiSiH3 has been determined by X-ray analysis. The compound crystallizes in space group C2/c with the cell dimensions a = 16.366(2), b = 11.458(1), c = 19.719(2) angstrom, beta = 110.93(1)degrees.
