The structure of the acylation products formed via solvent participation from pyrazolones was elucidated by IR and 1H NMR spectroscopy. Tautomerism of the parent compounds, syn-anti isomers of the 3-hydrazino-pyridazine type intermediates and constitutional isomers of their carbefchoxylated derivatives were studied.
