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- ...
