Preparation and properties of the (Me3Si)3SiX compounds (X = F, Cl, Br, I) are described and their NMR, IR and Raman spectra reported. A complete assignement of the vibrational spectra is given on the basis of a normal coordinate analysis. Si Si and Si X bonds are markedly weakened by the inductive effect of the Me3Si groups, compared with other SiSi and SiX compounds.
描述了(Me 3 Si)3 SiX化合物(X = F,Cl,Br,I)的制备和性质,并报道了其NMR,IR和拉曼光谱。在法向坐标分析的基础上,给出了振动谱的完整分配。与其他SiSi和SiX化合物相比,Me 3 Si基团的感应效应显着削弱了SiSi和SiX键。
