摘要

Abstracts: 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 (6H)-carboxylate as a carbonyl source under mild conditions. It is noteworthy that this process is mild, economic, and convenient. Key words: carbamate, symmetric urea, unsymmetric urea, carbonyl source, pyridazinone
