Structure of Low-Coordinated Phosphorus (III) Compounds Including Phosphorus-Nitrogen Multiple Bond: ¹³C, ¹⁵N and ³¹P NMR Investigation

Abstract

A wide series of low-coordinated phosphorus (III) compounds including iminophosphines 1, two- 2 or mono-coordinated 3 phosphorus-containing cations, and anion 4, where Mes∗ = 2,4,6-tris-(tert-butyl)phenyl, has been investigated by ¹³C, ¹⁵N and ³¹P NMR spectroscopy. The spectral parameters obtained are considered in connection with the ab initio (6–31G∗) calculation data of the model compounds.
