Studies of organophosphorochloridates. Part I. Synthesis of N-substituted phosphoramidic chlorides and acids

Abstract

Novel N-substituted phosphoramidic chlorides and acids have been prepared and their i.r. spectra are discussed. Pyrophosphoryl chloride has been used for the phosphorylation of amines. Treatment of NN′-diphenylphosphorodiamidic chloride with silver oxide gives NN′N″N‴-tetraphenylpyrophosphoramide, and not NN′-diphenylphosphenimidic amide as previously suggested. Some reactions of NN′-diarylphosphorodiamidic chlorides have been investigated.
