The present invention relates to new cyclic organophosphorus esters having the following structures: EQU1 where R is aryl or chloroalkyl of 2 to 10 carbon atoms, R' is aryloxy or chloroalkyloxy of 2 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 organophosphorus compounds have biological activity and are also useful as fire retardants, and as lead scavengers in gasoline.

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.

The present invention relates to new ureidophosphonic and phosphinic acids which are produced by hydrolysis of cyclic structures as follows: EQU1 where R is aryl or chloroalkyl of 2 to 10 carbon atoms, R' is OH or 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 organophosphorus compounds have biological activity and are also useful complex formers, as detergent builders and plating additives.
