| Abstract: | One new route for the synthesis of amino-substituted indazol-3,5-dione via the amidation reaction of o-carboxyazobenzenes is reported. Optimization which includes effects of the solvents, molar ratio of starting materials, and dehydrating agents on this reaction has been studied. A possible reaction mechanism has been proposed on the basis of the product's structure, and the steric hindrance could be the main reason for low yield. |
