Recent studies have demonstrated the capabilities of amidyl radicals to facilitate a range of intermolecular functionalizations of unactivated, aliphatic C-H bonds. Relatively little information is known regarding the important structural and electronic features of amidyl and related radicals that impart efficient reactivity. Herein, we evaluate a diverse range of nitrogen-centered radicals in unactivated

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.
