The copper-catalysed oxidative coupling of amines and H-phosphonates to produce phosphoramidates has been achieved using CuI as the catalyst and O2 (present in air) as the sole oxidant.
study on the iodine-mediated phosphoramidation reaction of amines and trialkyl phosphites was conducted, which not only disclosed the factors affecting the reaction but also revealed that it could proceed smoothly in CH2Cl2 at room temperature in open air. Using this method, various phosphoramidates with different aliphatic amines and aromatic amines were synthesized in good to excellent yields. Our

Investigation of the reactions of α-azidocarboxylic acids, N-(2-azidoethyl) amides and N-(2-azidoethyl) amines with trivalent P compounds shows that the intramolecular cyclization to spirophosphoranes of the intermediate phosphazo-compounds is typical of the azides of the first and third types but not of the second type. It is concluded that such cyclization is possible only where the functional group
