Article Preview

Abstract:

The reaction of 1,4,5,6-tetrahydro-6-pyridazinone-3-carboxylic acid hydrazides (1) and 1,6-dihydro-6-pyridazinone-3-carboxylic acid hydrazides (2) with four kind of substituted 3-formyl chromones (3a-3d) and five kind of 1-phenyl-3-aryl-4-formylpyrazoles (3e-3i) afforded the new compounds aldehyde hydrazones (4a-4i) and (5a-5i). Their structures were established by IR, 1H NMR and elemental analysis.
