✦ Synopsis

The AG* values for the barrier to rotation around the P-N bond have been determined in some aminophosphines and are dependent on the substituents bound to the phosphorus atom. The comparison between 3J(P-N-C-H) and AG* values indicates that p,-d,

The signs of the phosphorus-proton coupling constants in various allenic organophosphorus compounds have been determined by either analysis of the AB2X spectra or double resonance. Probable absolute signs have been obtained by taking sJ(P-H) as positive. In allenic phosphine oxides, the following s
