Preparation and spectroscopic properties of amines containing germyl and difluorophosphino-groups

Abstract

The compounds PF₂[NH(GeH₃)], PF₂[N(GeH₃)₂], PF₂[N(GeH₃)(SiH₃)], and N(GeH₃)(PF₂)₂ have been prepared from the appropriate primary and secondary difluorophosphinoamines by reaction with germyl halide and trimethylamine. The compounds are all much more stable than trigermylamine, but decompose at room temperature by elimination of GeH₂. Vibrational, photoelectron, n.m.r., and mass spectroscopic data have been recorded, and are interpreted in terms of the probable conformations adopted by the fluorophosphino-groups.
