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。
