  摘要：

  1,2-Bis(p-tolyl)disilane (2) has been prepared through Wurtz-coupling of chloro(p-tolyl)silane using lithium metal. It was used as a precursor for 1,2-bis(trifluoromethanesulfonyloxy)disilane (1), which was obtained by treatment with two equivalents of trifluoromethanesulfonic acid. This intermediate was treated with n-BuLi, n-HexLi or n-OctMgBr to give the title compounds (n-CnH2n+1)SiH2SiH2(n-CnH2n+1) (n = 4,6,8), 4a-c. Treatment of 2 with only one equivalent of triflic acid gave p-TolSiH(2)SiH(2)OSO(2)CF(3) (5), which can be selectively converted into mixed alkyl-aryl-disilanes with LiR reagents, e.g. (n-Bu)SiH2SiH2(p-Tol), 6. The crystal structure of compound 2 has been determined by an X-ray diffraction study; it has a staggered trans-conformation with a crystallographic center of inversion.

  The catalytic reactions between monosilane or disilane and 1-hexene or 1,5-hexadiene were studied. The reactions with monosilane gave the silylated compounds in the presence of a platinum complex, LiAlH4 and a radical initiator. In the reactions with disilane, the same silylated compounds were produced in the presence of a platinum complex as in the reaction with monosilane, and disilanylated compounds
