range of N-(amidomethyl)-polyhalosilanes have been measured in solution and the extent of SiO 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 SiO bond is almost fully formed.
