Contributions to the Chemistry of Boron, 200. - B-Functional Diboryl-silyl- and Boryl-silyl-stannyl-aminesStannazane cleavage of Cl3-nMenSiN(SnMe3)2 with an excess of BCl3 leads to bis(dichloroboryl)silylamines Cl3-nMenSiN(BCl2, 2-chlor-1,3,2-dithiaborolane, or 2-chloro-1,3,2-benzodioxaborole produce boryl-silyl-stannyl-amines of type X2BN(SiMe3)SnMe3 (2a-c). Cl2BN(SiCl3)SnMe3 (3) is obtained similarly from BCl3 and Cl3SiN(snMe3.)2. 3 decomposes on heating with SnN cleavage and formation of (Cl3SiN=BCl)4 (4). Asymmetrically substituted diborylamines Me3SiN(BX2)-BY2 are prepared by substitution reactions using Me3SiN(BCl2)BY2 or by stannazane cleavage of Y2BN(SiMe3)SnMe3 (2) and an appropriate boron halide. Constitution and conformation of the new diboryl-amines are deduced from multinuclear resonance spectra.
