Abstract
The influence of solvent on the tautomerism on N1 substituted pyrazolin‐5‐ones has been investigated.As a general rule, the percentage of CH form is always bigger in apolar solvents and decreases in aprotic solvents with increasing basicity, probably in favour of the OH form.In protic solvents, the concentration of NH form is related with hydroxylic solvents acidity.Keywords
