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.

Herein, we report a highly efficient ZnI2 -triggered oxidative cross-coupling reaction of P(O)-H compounds and amines. This operationally simple protocol provides unprecedented generic access to phosphinic amides/phosphoramidate derivatives in good yields and short reaction time. Besides, the reaction proceeds under mild conditions, which avoids the use of hazardous reagents, and is applicable to scale-up
