Microwave-assisted synthesis and antifungal activity of some new 1H-1,2,4-triazole derivatives
(0-Belirlenecek, 2008)
A number of 3-aryl-4-arylmethylideneamino-4,5-dihydro-1H-1,2,4-triazol-5- ones were synthesized by reaction of the corresponding aromatic aldehydes with 4-amino-3-aryl-1H-1,2,4-triazol-5-ones in anhydrous ethanol under ...
3-Ethyl-4-(p-chlorobenzylidenamino-4,5-dihydro-1H-1,2,4-triazol-5-one (EPHBAT) as precipitant for carrier element free coprecipitation and speciation of chromium(III) and chromium(VI)
(0-Belirlenecek, 2009)
A method for the separation and speciative determination of Cr(VI) and Cr(III) has been developed. The procedure is based on coprecipitation of Cr(III) on 3-ethyl-4-(p-chlorobenzylidenamino-4,5-dihydro-1H-1,2,4-triazol-5-one ...
Determination of the protonation constants of triazole derivatives in non-aqueous solvents
(0-Belirlenecek, 2009)
Different 17 triazole derivatives were titrated with tetrabutylammonium hydroxide in four non-aqueous solvents (isopropyl alcohol, rert-butyl alcohol, N,N-dimethylformamide and acetonitrile), using Potentiometric method. ...
Synthesis of 1,2,4-Triazole derivatives and determination of protonation constant
(0-Belirlenecek, 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 ...
Synthesis of some N-alkoxycarbonyl-N?-benzoyl-benzamidrazones(p- toluamidrazones) and 1,3,5-trisubstituted 1,2,4-triazole derivatives from N-benzoylimidates and their antimicrobial and anticancer screening studies
(0-Belirlenecek, 2007)
Some new N-alkoxycarbonyl-N?-benzoyl-benzamidrazones (p-toluamidrazones) 3a-3d, and 1,3,5-trisubstituted 1,2,4-triazole 4a-4h derivatives by starting from N-benzoylbenzimidates or N-benzoyl-p-toluimidates. The structures ...
Microwave-assisted and conventional synthesis of new phthalocyanines containing 4-(p-fluorophenyl)-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one moieties
(0-Belirlenecek, 2007)
New metal-free and metal (Zn, Ni, Cu and Co) phthalocyanines containing 4-(p-fluorophenyl)-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one moiety have been prepared from 1-(3,4-dicyanophenyl)-4-(p-fluorophenyl)-3-methyl-4,5- ...
Studies on the protonation constants of some triazoles in ethanol-water mixtures
(0-Belirlenecek, 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 ...
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
(0-Belirlenecek, 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 ...
Synthesis and anticancer evaluation of some new 4-amino-3-(p-methoxybenzyl) -4,5-dihydro-1,2,4-triazole-5-one derivatives
(Verlag der Zeitschrift fur Naturforschung, 2008)
4-Amino-3-p-methoxybenzyl-5-oxo-4,5-dihydro-1,2,4-triazol-1-yl-acetic acid ethyl ester (2) was prepared from 4-amino-4,5-dihydro-1H-1,2,4-triazole-5-one (1) and ethyl bromoacetate. Compound 3 was synthesized by the ...
Synthesis and properties of triazol-5-one substituted phthalocyanines by microwave irradiation
(0-Belirlenecek, 2006)
Triazol-5-one substituted phthalocyanines were prepared quickly by the reaction of 4-nitrophthalonitrile with anhydrous metal salts in DBU (1,8-diazabicyclo[5,4,0]undec-7-ene) and DMAE (dimethylaminoethanol) by microwave ...
