The title compound 3 has been prepared from diphenyl carbonate, phosphorus pentachloride and sulfamide 2. It appears to be a useful synthetic building block for acyclic and heterocyclic compounds containing the N-SO2-N-moiety, for example, 3-sulfamoylisoureas, 4-sulfamoylisosemicarbazides, 2-sulfamoylguanidines, imid-, ox- and thiazolidines, 1,2,6-thiadiazine 1,1-dioxides, 1,2,4,6-thiatriazine 1,1-dioxides.
标题化合物 3 由碳酸二苯酯、五氯化磷和硫酰胺 2 制备而成。它似乎是含有 N-SO2-N 键的无环和杂环化合物的有用合成构件,例如 3-氨基甲酰基异脲类、4-氨基甲酰基异氨基脲类、2-氨基甲酰基胍类、亚胺类、氧化类和噻唑烷类、1,2,6-噻二嗪 1,1-二氧化物、1,2,4,6-噻三嗪 1,1-二氧化物。
