Rapid and efficient microwave-assisted synthesis of some new triazol-3-one derivatives
(Wiley, 2013)
A growing body of literature has shown the effectiveness of using microwaves in chemical reactions. The aim of this study is to demonstrate a rapid and highly efficient synthesis of some new triazol-3-ones via microwave ...
Experimental and computational studies on 4-[(3,5-dimethyl-1H-pyrazol-1-yl) methoxy]phthalonitrile and synthesis and spectroscopic characterization of its novel phthalocyanine magnesium(ii) and tin(ii) metal complexes
(Elsevier B.V., 2013)
The molecular structure of the substituted phthalonitrile was analyzed crystallographically and compared with optimized geometric structure. The structural properties of the compound such as energy, vibrational frequency, ...
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. ...
Synthesis and in vitro antioxidant activities of novel 4-(3-methyl-2- thienylmethyleneamino)-4,5-dihydro-1H-1,2,4-triazol-5-one derivatives with their acidic properties
(2013)
In the present study 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5- ones 2a-i reacted with 3-methyl-thiophene-2-carboxyaldehyde to afford the corresponding 3-alkyl(aryl)-4-(3- methyl-2-thienylmethyleneamino)-4,5-dihydro- ...
Evaluation of phenolic compounds in Tilia rubra Subsp. caucasica by HPLC-UV and HPLC-UV-MS/MS
(Taylor & Francis Ltd., 2014)
Profile of phenolic compounds of Tilia rubra subsp. caucasica was measured by high performance liquid chromatography coupled with ultraviolet and tandem mass spectroscopy. Three different extraction methods (methonolic, ...
