Synthesis and NMR Characterization of Heteroarene Substituted N-Silylphosphoranimines.

摘要

Several of the title compounds were prepared by application of the Peterson olefination reaction to the C-silylated phosphoranimine. Because of their importance as phosphazene precursors, we are currently studying the derivative chemistry of these N-silylphosphoranimines. These new phosphoranimines generally formed as mixtures of cis and trans isomers, were obtained as distillable liquids in yields of 60-75% and were fully characterized by NMR (1H, 13C, and 31P) spectroscopy and elemental analyses.
