The selective syntheses of carbamates, symmetric ureas, and unsymmetrical ureas have been accomplished by the reaction of amines with phenyl 4,5-dichloro-6-oxopyridazine-1(61H)-carboxylate as a carbonyl source under mild conditions. It is noteworthy that this process is mild, economic, and convenient.
氨基甲酸酯、对称脲和不对称脲的选择性合成是通过胺与苯基 4,5-dichloro-6-oxopyridazine-1(61H)-carboxylate 作为羰基源在温和条件下反应完成的。值得注意的是,该过程温和、经济、方便。
