Abstract The isomeric 3-(hydroxyphenyl)-1,4,5,6-tetrahydropyridazines differ from their five-membered-ring analogs, the 3-(hydroxyphenyl)-Δ2-pyrazolines, in their behavior in catalytic-decomposition reactions. The catalytic conversion of 3- (hydroxyphenyl)-1,4,5,6-tetrahydropyridazines takes place at 120–200° C, dehydrogenation being the main reaction. The hydroxyphenylpyrazolines, under the same conditions, undergo decomposition with liberation of nitrogen and formation of the corresponding cyclopropanes.
