The acid hydrolysis of a series of N-substituted diphenyl and di-n-butyl phosphoramidates has been studied. The N-methyl compounds were the most readily hydrolysed; in refluxing 25% aqueous formic acid, specific cleavage of the P–N bond was complete in a few minutes.
Substitution of diarylphosphoryl azides with aliphatic amines catalyzed by simple rare‐earth metal salts: Efficient and novel preparation of phosphoryl amides
A novel and high efficient protocol was disclosed herein for the rare-earth metal salt-catalyzed substitution of phosphorylazides with amines. In this homogeneous catalysis system, different diarylphosphoryl azides and aliphatic and aromatic amines were evaluated under the optimized reaction conditions, and a series of phosphoryl amides were generated through LaCl3 catalysis for the first time in

AbstractMass spectra of 38 organophosphorus compounds, containing both phosphate ester (P(O)OR) and phosphoramidate (P(O)NR′R″) functional groups, were recorded and discussed. Attention was focused on PN bond cleavage, which can involve simple fission, fission accompanied by hydrogen migration from the ester group and fission accompanied by the migration of the ester R group to the departing nitrogen atom. Fragmentations characteristic for the N(β‐chloroethyl) derivatives (phosphorylated nitrogen mustards) are also presented.
