Abstract:

Proton magnetic resonance and infrared spectra were obtained for 44 carbamylphosphonates and related compounds, the common structural features being the grouping [Equation]

As with ordinary amides, slow rotation is observed around the carbonyl-to-nitrogen bond, but the chemical shift between nitrogen substituents is three to five times as great. Evidence is presented for long range coupling of phosphorus to protons in N-substituents. Correlations are observed between the carbonyl and phosphoryl stretching frequencies and substituents both on nitrogen and on phosphorus.
