Dependence of tautomerism on substituent type in o-hydroxy Schiff bases
Autor: Çiğdem Albayrak Kaştaş, Gökhan Kaştaş
Publikováno v: Macedonian Journal of Chemistry and Chemical Engineering, Vol 38, Iss 1, Pp 85-94 (2019)
Quantum computational methods were used to elucidate the structures of the o-hydroxy Schiff bases with different substituents. It is possible for a Schiff base to have different tautomeric structures depending on intramolecular proton transfer from t
