Investigation of the structure and the properties of the potentially tautomeric 1,2-dihydro-5,7-dimethyl-6H-pyrrolo[3,4-d]pyridazine-1-ones in the gas and aqueous phases using semiempirical methods
(Elsevier Science BV, 1998)
Potentially tautomeric 1,2-dihydro-5,7-dimethyl-6H-pyrrolo[3,4-d]pyridazine-1-ones and their fixed tautomeric forms have been studied, in order to predict their tautomeric equilibrium constants and pK(a) values, using ...
Protonation, tautomerization and valence tautomerization of selected imidazo[4,5-f]quinolines. A theoretical study of gas and liquid basicity of imidazo[4,5-f]quinolines
(1993)
The theoretical calculations on imidazo[4,5-f] quinolines has shown that the first protonation takes place at the pyridine, nitrogen atom rather than at the imidazole nitrogen atom. The preferred tautomeric form was found ...
