The phosphorus–nitrogen bond. Synthesis, characterization, and infrared studies of heterocyclic phosphoryl (phosphetan) amides

Abstract

Several new amide derivatives of the heterocyclic 2,2,3,4,4-pentamethylphosphetan 1-oxide (1) have been prepared by heating together the corresponding chloride and amine at elevated temperatures. The products have been characterized by 1H and 13P n.m.r. spectroscopy and in particular by i.r. spectroscopy over the range 400–4000cm–1. In one case a mass spectrum is reported in detail. Evidence for hindered rotation about the P–N bond is discussed and interpreted in terms of pπ–dπ contributions to the bonding.
