The protonation site of hydrazones and related tautomeric forms can change with the solvent or kind of hydrazine or carbonyl compound moieties. The protonation of the β-nitrogen of hydrazones group in Scheme 5 is therefore also plausible; for more details, see: (a) Zverev V.V., Bazhanova Z.G., Ermolaeva L.V. Seriya Khimicheskaya.
