  Reactions of sulphur diimides with di- and tri-silanes: 15N and 29Si nuclear magnetic resonance study and the crystal structure of bis[tert-butyl(trichlorosilyl)amino]sulphane

  摘要：

  Sulphur diimides R1NSNR2 1a (R1 = R2 = Bu(t)), 1b (R1 = Bu(t), R2 = Me3Si) and 1c (R1 = R2 = Me3Si) react with tetrachloro-1,2-dimethyldisilane 2, hexachlorodisilane 3 and octachlorotrisilane 6 by cleavage of the Si-Si bond to give the corresponding diaminosulphanes (4, 5, 7) in quantitative yield. In the case of 6 only one of the two Si-Si bonds is cleaved. The reaction between 1b and 6 affords two isomers in a ratio close to 1:1 which suggests the intermediacy of a cyclic adduct prior to the intramolecular redox process. The products have been characterized by H-1, C-13, N-15 and Si-29 NMR spectroscopy in solution as well as by Si-29 cross polarization magic angle spinning NMR in the solid state. The crystal structure of (Cl3Si)Bu(t)NSNBu(t)(SiCl3) 5a (prepared from 1a and 3) has been determined: space group Pbcn (no. 60), with a = 2212.9(6), b = 1172.4(3), c = 2160.5(8) pm, and Z = 12.
