New Preparative Chemistry of Silicon-Nitrogen-Phosphorus Compounds

Abstract

Compounds containing the Si-N-P linkage, especially (silylamino)phosphines, (Me₃Si)₂NPR₂, and N-silylphosphoranimines, Me₃SiN=PR₂X, are of interest as precursors to polyphosphazenes and/or other phosphorus-based polymer systems or to new types of organophosphorus or phosphorus-nitrogen compounds. In addition to reviewing the general preparative chemistry of these Si-N-P systems, this report describes some recent results on the synthesis and characterization of three new types of P-N compounds that either contain or were prepared from Si-N-P linkages. The new systems include; (1) a series of acetylene-substituted (silylamino)phosphines and N-silylphosphoranimines, (2) three types of aminoborane derivatives of N-silylphosphoranimines, and (3) several N-phosphoryl substituted phosphoranimines.
