The present invention relates to new compounds containing urea and organophosphorus amide moieties in cyclic structures as shown in the following equation: ##EQU1## where R is aryl or chloroalkyl of 2 to 10 carbon atoms, R' is aryl of 6 to 10 carbon atoms, R" is hydrogen, alkyl, alkenyl, furanyl or aryl of 1 to 15 carbon atoms and substituted aryl forms where the substituent is fluorine, chlorine, bromine, cyano, hydroxyl, alkyloxy, alkylthio or mixtures of such substituents, and Y is O or S. The cyclic organophosphorus amides have biological activity and are also useful as fire retardants and as lead scavengers in gasoline.
