  Bromination and iodination of hydrosilanes and germanes were studied. Treatment of hydrosilanes with an excess of ethyl, propyl, or allyl bromide in the presence of a catalytic amount of PdCl2 or NiCl2 gave bromosilanes in good to high yield by hydrogen–halogen exchange. By using methyl, propyl, or allyl iodide as the iodine source, similar iodination of hydrosilanes was readily performed. Halogenation

  研究了氢硅烷和锗烷的溴化和碘化。在催化量的PdCl 2或NiCl 2存在下，用过量的乙基，丙基或烯丙基溴处理氢硅烷，可通过氢-卤素交换以高至高收率得到溴硅烷。通过使用甲基，丙基或烯丙基碘作为碘源，可以容易地进行氢化硅烷的类似碘化。水锗烷的卤化也通过类似的处理进行。

  Siloxane linkages are formed non-hydrolytically by the reaction of dihalogenosilanes with either dibenzylether, or dibenzyloxysilanes and dibenzhydryloxysilanes. The heterocondensation reaction is activated in the presence of NaI (in acetonitrile) or fluoride anions. This offers an alternative copolymerization route to the usual dehydrocondensation of SiOH-terminated species. Thus, the title copolymer was prepared by reaction of equimolar amounts of Me(2)Si(OCHPh(2))(2) and 1,4-bis(chlorodimelhylsilyl)benzene at 100 degrees C. The Si-29 NMR spectrum supports a quasi-random sequence in the copolymer. Thermal stability is similar to that reported for an alternating microstructure, as inferred from thermogravimetric analysis.
