The present invention relates to new nitrogen-containing organophosphorus compounds having aryloxy substituents bonded to phosphorus in ester structures. ##STR1## WHERE R' is aryl or alkyl-substituted aryl of 6 to 10 carbon atoms, 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, or CS. The phosphorus compounds have utility as fire retardants and as biologically active materials.
本发明涉及新的含氮有机磷化合物,其在酯结构中与磷相连的是芳氧基取代基。其中R'是含有6至10个碳原子的芳基或烷基取代的芳基,R"是含有1至15个碳原子的烷基、烯基或芳基,以及取代芳基形式,其中取代基是氟、氯、溴、硝基、氰基、羟基、烷氧基或这些取代基的混合物,Z是CO或CS。这些磷化合物具有阻燃剂和生物活性材料的用途。
