Microwave-assisted synthesis of novel 2,4-dihydro-5-[4-(trifluoromethyl) phenyl]-3h-1,2,4-triazol-3-ones and potentiometric determination of their pKa in nonaqueous solvents
(Wiley, 2010)
The novel 4-amino- or 4-aryl-substituted 2,4-dihydro-5-[(4-trifluoromethyl) phenyl]-3H-1,2,4-triazol-3-ones 3a-3g were synthesized by reaction of N-(ethoxycarbonyl)-4-(trifluoromethyl)benzenehydrazonic acid ethyl ester (2) ...
Synthesis of some benzimidazole-thiophene hybrids as potential urease and lipase inhibitors
(Springer Link, 2023)
In this study, some benzimidazole-thiophene hybrid compounds containing isatin and salicyl moieties were synthesized and investigated for their urease and lipase inhibition properties. Most of the synthesized compounds ...
Developing effective antimicrobial agents: synthesis and molecular docking study of ciprofloxacin-benzimidazole hybrids
(Wiley, 2024)
In this study, we designed and synthesized some new ciprofloxacin-benzimidazole hybrid compounds and evaluated them for their antimicrobial activity against four Gram-positive (B. subtilis, B. megaterium, E. faecalis and ...
Synthesis of novel triazol compounds containing isatin as potential antibacterial and antifungal agents by microwave and conventional methods
(Sage Publishing, 2011)
Microwave irradiation has been used to accelerate the conversion of isatin (1a) and 5-nitroisatin (1b) into their Schiff bases 3-[5?-aryl(alkyl)- 2?,4?-dihydro-1?,2?,4?-triazol-3?-on- 4?-yl]iminoisatin (3a-g) and ...
Microwave-assisted synthesis of some new benzylidenamino compounds and potentiometric determination of their pKa

(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. ...
An efficient synthesis of some new bisbenzimidazoles via microwave technique
(2014)
2,2’-[1,4 (1,3)-Phenylenedi(methylene)]bis-1 H -benzimidazole derivatives were obtained from the reaction of 1,4- or (1,3)-bisiminoester hydrochloride and o -phenylenediamine derivatives under microwave irradiation. Ester ...
