1,3-Dipolar cycloaddition of perfluoroalkyl ethyle azides 1 with isocyanates 2 afforded 1-perfluoroalkyl-4-(n-Bu, phenyl or mesitylsulfonyl) tetrazol-5-ones 3 in good yields. The use of perfluoroalkyl ethylazides extends the reaction to the less reactive n-butyl isocyanate.

GRAPHICAL ABSTRACT Abstract The synthesis of new unsaturated N-sulfonylcarbamates by the addition of unsaturated alcohols to aroxy(alkoxy)sulfonylisocyanates is reported. The reaction is carried out at room temperature in the presence or absence of solvent, depending on the nature of the starting alcohol. The products were obtained in good yields and characterized with IR, 1H, and 13C NMR and HRMS

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。
