THE TAUTOMERISM OF PYRAZOLINES (DIHYDROPYRAZOLES)

THE TAUTOMERISM OF PYRAZOLINES (DIHYDROPYRAZOLES)

The exception to the rule that Δ3-pyrazolines are not stable unless both nitrogen atoms are substituted that has been recently published, Tetrahedron Lett. 55, 2208, (2014), has been proved false. By means of GIAO/B3LYP/6-311++G(d,p) calculations, it has been shown that the product is a pyr...
