  Structure and dynamics of hindered organosilicon compounds. The conformations of symmetrical (Me3Si)3C and (PhMe2Si)3C derivatives

  摘要：

  At low temperatures the methyl region of the H-1 and C-13 NMR spectra of (Me3Si)3CSiCl3 and the H-1 NMR spectrum of (Me3Si)3CSiBr3 each show three signals of equal intensity and the Si-29 NMR spectrum of the trichloride shows only one Me3Si signal. These data are consistent with the methyls within each Me3Si group becoming inequivalent. Compounds containing the (PhMe2Si)3C group are able to adopt different conformations at low temperature; in (PhMe2Si)3CSiCl3 the phenyl groups mesh together while in (PhMe2Si)3CBr they are separated by methyl groups. These different arrangements of the ligand can readily be distinguished by H-1 NMR spectroscopy, and the conformation in the case of (PhMe2Si)3CSiCl3 has been confirmed in the solid state by X-ray crystallography.
