Displacement of phenol from a phenyl ester of phosphoric acid or a phosphoramidic acid by anions of certain amines or phosphoramidates in the presence of a base results in the formation of P-N and P-N-P bonds. From (C6H5O)3PO and NaNHC6H5 there was obtained (C6H5O)2P(O)NHC6H5; with NaN(C6H5)2, the product was (C6H5O)2P(O)N(C6H5) 2. From (C6H5O)3PO and sodium amide, however, the product was (C6H5O)2P(O)NHP(O)(OC6H 5)2. From (C6H5O)2P(O)NH2, by self-condensation, was obtained both (C6H5O)2P(O)NHP(O)(OC6H 5)NH2 and (C6H5O)2(O)NHP(O)(OC6H 5)NHP(O)(OC6H5)NH2. From (C6H5O)3PO and (C6H5O)2P(O)NH2 the principal product was (C6H5O)2P(O)NHP(O)(OC6H 5)NHP(O)(OC6H5)2. The last three compounds have not been reported before. The properties of these compounds and their metal and amine derivatives are described.
