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.
本发明涉及一种新的化合物,其中含有
尿素和有机
磷酰胺基团,其在循环结构中如下所示:##EQU1## 其中R为含有2至10个碳原子的芳基或
氯代烷基,R'为含有6至10个碳原子的芳基,R"为氢、烷基、烯基、
呋喃基或含有1至15个碳原子的芳基和取代芳基形式,其中取代基为
氟、
氯、
溴、
氰、羟基、烷氧基、烷
硫基或这些取代基的混合物,Y为O或S。这些循环有机
磷酰胺具有
生物活性,并且在防火剂和汽油中作为
铅清除剂也很有用。
