Nature of the pentamethyldisilanyl group in organosilicon compounds

  • 18 Accesses


The positige inductive effect of the pentamethyldisilanyl group (CH3)3SiSi(CH3)2 and the election-acceptor effect of its pπ-dπ bond with an aromatic ring are appreciably greater than the analogous effects of the trimethylsilyl group (CH3 3Si, which gives ground for the postulation of the presence of a pπ-dπ-d1π bond in the fragment Csp 2-Si-Si.
