Abstract Reaction of carboxylic acids with aroxy(alcoxy)sulfonylisocyanates allowed the preparation of the corresponding aroxy(alcoxy) N-acylsulfamates. With succinic diacid, the same reaction yielded the corresponding N, N′-diacylsulfamates, whereas the N, N′-disulfonylureas were obtained by reaction of maleic or fumaric diacids.
摘要 羧酸与芳氧基(烷氧基)磺酰基异氰酸酯反应可以制备相应的芳氧基(烷氧基)N-酰基氨基磺酸盐。对于琥珀二酸,同样的反应产生相应的 N, N'-二酰基氨基磺酸盐,而 N, N'-二磺酰脲是通过马来酸或富马酸二酸的反应获得的。
