Determination of the pKa of Some triazole derivatives by the potentiometric method in dioxan-water mixtures
(2011)Stoichiometric protonation constants of some 3-alkyl(aryl)-4-(substituted benzylamino)-4,5-dihydro-1 H-1,2,4-triazol-5-ones derivatives were determined potentiometrically in 50% (v/v) dioxan-water mixtures at 25°C with an ... -
Determination of the protonation constants of some 4-(substituted benzylamino)-4,5-dihydro-1H-1,2,4-triazol-5-ones by the potentiometric method in ethanol-water mixtures
(2007)To gain more information about the effect of solvent on 4,5-dihydro-1H-1,2,4-triazol-5-ones, the stoichiometric protonation constants of thirteen triazoles in ethanol-water mixtures were determined at an ionic strength of ... -
Microwave-assisted synthesis of some 1, 2, 4-triazol-3-ones and potentiometric determination of their pKa in amfiprotic and dipolar aprotic-water mixtures
(0-Belirlenecek, 2013)The novel 5-alkyl(aryl)-4-(aryl)-2, 4-dihydro-3H-1, 2, 4-triazol-3-ones (1-12) were synthesized by reaction of (N?-ethoxycarbonyl)-4-alkyl(aryl)hydrazonic acid ethyl ester with primary amines by microwave irradiation. ... -
Studies on the protonation constants of some triazoles in ethanol-water mixtures
(Chemical Publishing Co., 2008)Several studies, involving the formation and investigation of biological activities of some triazoles derivatives. These derivatives have weak acidic properties. To gain more information about the effect of solvent on ... -
Synthesis of 1,2,4-Triazole derivatives and determination of protonation constant
(2009)A microwave irradiation method has been developed for the synhesis of some 1,2,4-triazole derivatives using environmentally benign solvent ethanol in open vessels. Twelve 1,2,4-triazole derivatives were synthesized in good ...
