摘要: 3-Cyano-7-diethylamino-N-ethoxycarbonyl-iminocoumarin reacted with different hydrazines as N-nucleophiles to afford, in one step, a new series of 2-N-substituted 3-triazolonyl-iminocoumarins good yields. In two cases, N-unsubstituted derivatives were also obtained. The structures all the products obtained confirmed by infrared, 1H NMR, 13C and elemental analysis. optical properties three these compounds dichloromethane ethanol reported.
