Microwave-assisted synthesis and biological evaluation of some benzimidazole derivatives containing a 1,2,4-triazol ring
(Wiley-V C H Verlag Gmbh, 2013)
A new series of 2-(4-(trifluoromethyl)phenyl)-1H-benzo[d]imidazole derivatives containing a 1,2,4-triazole ring were synthesized via microwave technique. This efficient procedure provides pure products within a few minutes. ...
Efficient synthesis of 5-(substituted)benzyl-2,4-dihydro-3H-1,2,4-triazol- 3-ones using microwave irradiation
(2013)
A growing body of literature has shown the effectiveness of using microwave irradiation in chemical reactions. The aim of this study is to demonstrate a rapid and highly efficient synthesis of some new 5-aryl-2,4-dihydro-3H-1,2,4- ...
A Novel route to one-pot three-component synthesis of benzimidazo [2,1-b]-quinazolin-1-one derivatives
(Bentham Science Publ Ltd, 2013)
One-pot three-component synthesis of benzimidazo[2,1-b]-quinazolin-1-ones was efficiently performed under microwave irradiation and solvent-free condition. the method provides some advantages such as low cost, experimental ...
Microwave-assisted synthesis of some 1H-1,2,4-triazol-3-one derivatives
(Bureau Scientific Publ, 2013)
4-Amino-5-(methyl/ethyl)-2,4-dihydro-3H-1,2,4-triazol-3-one were synthesized from the reaction of (methyl/ethyl)-ester ethoxycarbonyl hydrazone with hydrazine hydrate and then, converted to corresponding Schiff bases using ...
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. ...
