The present invention relates to new nitrogen-containing organophosphorus compounds having aryloxy or aryl substitutents bonded to phosphorus in ester or phosphine oxide structures. ##EQU1## R is alkyl, bromoalkyl, chloroalkyl or aryl of 1 to 10 carbon atoms, R' is R or OR with the proviso that at least one R' is aryl or aryloxy, R" is hydrogen, alkyl, aryl or haloaryl of 1 to 15 carbon atoms, or no more than one carboethoxymethyl group, and where the halogen on the aryl group is bromine, chlorine or fluorine, R'" is alkyl, alkenyl or aryl groups of 1 to 15 carbon atoms and substituted aryl forms where the substituent is fluorine, chlorine, bromine, nitro, cyano, hydroxyl, alkyloxy or mixtures of such substituents, and Z is CO, CS or SO.sub.2. The phosphorus compounds have utility as fire retardants and as biologically active materials.
