摘要：

The Si-29- and C-13-NMR spectral parameters of a range of N-(amidomethyl)-polyhalosilanes have been measured in solution and the extent of Si-O bond formation and pentacoordination determined. The larger the number of electronegative groups attached to the silicon the greater the extent of pentacoordination achievable by the silicon. Thus with trichlorosilanes a 'tight' pentacoordinate silicon is observed where the Si-O bond is almost fully formed. (C) 2000 Published by Elsevier Science S.A. All rights reserved.
