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 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
(2012)
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 benzylidenamino compounds (4a-f) ...
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 ...
Synthesis of benzimidazoles containing piperazine ring as potential therapeutic agents against diabetes mellitus and antioxidant activities
(Elsevier, 2024)
We synthesized a novel 6-(4-substitue-piperazin-1-yl)-2-aryl-1H-benzimidazole derivatives starting from 5-(4-substitue-piperazin-1-yl)-2-nitroaniline with different aldehydes. A quick "onepot" nitro reductive cyclization ...
Green protocol: Catalyst-free synthesis of 2-substituted benzimidazoles under ultrasound irradiation
(Science Reviews 2000 Ltd, 2018)
The synthesis of 2-substituted benzimidazoles from the reaction of o-phenylenediamine and an imino ester hydrochloride with ultrasound irradiation is reported. The procedure has an eco-friendly and simple workup with good ...
A new green protocol for the synthesis of 2-substituted perimidines from hydrazones under catalyst- and solvent-free conditions
(Bulgarian Academy of Sciences, 2018)
A new green protocol was developed for the synthesis of 2-substituted perimidines. The protocol involves a reaction of ethoxy carbonylhydrazone with 1,8-diaminonaphthalene under solvent- and catalyst-free conditions. Simple ...
