Synthesis of unsymmetrical 3,5-disubstituted 1,2,4-triazole derivatives with their pKa values
(Chiminform Data S A, 2014)
Acylhydrazones (2a-b) were synthesized by the condensation of iminoester hydrochlorides (1a-b) with benzhydrazide. the treatment of acylhydrazones With hydrazine hydrate afforded 4-amino-4H-1,2,4-triazoles. (3a-b). ...
Determination of the pKa value of some 1,2,4-triazol derivatives in forty seven different solvents using semi-empirical quantum methods (PM7, PM6, PM6-DH2, RM1, PM3, AM1, and MNDO) by MOPAC computer program
(Ovidius University Press, 2023)
In this study, we calculated the enthalpy (?H, kcal/mol), entropy (?S, cal/K.mol) and free energy (?G, kcal/mol) thermodynamic values of each molecule for forty-seven different solvent media according to semi-empirical ...
