The present invention concerns a new process for the production of organophosphorus compounds having sulfonamide substituents. ##STR1## where R is aryl or chloroalkyl of 2 to 10 carbon atoms, R' is aryl, aryloxy or chloroalkyloxy of 2 to 10 carbon atoms, R" is alkyl, aryl, haloaryl or alkaryl of 1 to 15 carbon atoms, where the aryl halogen is bromine, chlorine or fluorine, and R'" is hydrogen alkyl, alkenyl or aryl of 1 to 15 carbon atoms and substituted aryl forms wherein the substituent is fluorine, bromine, chlorine, hydroxyl, alkyloxy or mixtures of such substituents. These sulfonamide phosphorus compounds have utility as fire-retardants and as biologically active materials.
本发明涉及一种用于生产具有
磺胺基取代基的有机
磷化合物的新工艺。其中R为芳基或含
氯烷基,碳原子数为2至10;R'为芳基、芳氧基或含
氯烷氧基,碳原子数为2至10;R"为碳原子数为1至15的烷基、芳基、卤代芳基或烷芳基,其中芳基卤素为
溴、
氯或
氟;R'"为氢、烷基、烯基或碳原子数为1至15的芳基,以及取代芳基形式,其中取代基为
氟、
溴、
氯、羟基、烷氧基或这些取代基的混合物。这些
磺胺基
磷化合物可用作阻燃剂和
生物活性材料。
