Synthesis, spectroscopic studies, and antioxidant activities of novel thio/carbohydrazones and bis-isatin derivatives from terephthalaldehyde
(Scientific Technical Research Council Turkey-Tubitak, 2020)
New bis(isatins-thio/carbohydrazones) based on Schiff bases were prepared from terephthalaldehyde biscarbohydrazone and 5-substituted isatins in the presence of a drop of sulfuric acid under reflux in ethanol. Terephthalaldehyde ...
Novel carbohydrazones including 5-substituted isatin: Synthesis, characterization, and quantum-chemical studies on the relationship between electronic and antioxidant properties
(Pergamon-Elsevier Science Ltd, 2020)
1-(5-Chloro-2-oxoindolin-3-ylidene)carbohydrazone (1), 1-(5-fluoro-2-oxoindolin-3-ylidene)carbohydrazone (2), 1-(5-methoxy-2-oxoindolin-3-ylidene)thiocarbohydrazone (3), and 1-(5-methoxy-2-oxoindolin-3-ylidene) carbohydrazone ...
Synthesis, characterization, antioxidant, and antibacterial activities of new 2,3-dimethoxy and 3-acetoxy-2-methyl benzamides
(Springer, 2020)
We performed a series of novel benzamide compounds which were synthesized starting from 2,3-dimethoxybenzoic acid or 3-acetoxy-2-methylbenzoic acid and amine derivatives. All the obtained products were purified, and the ...
Two new benzamides: Synthesis, spectroscopic characterization, X-ray diffraction, and electronic structure analyses
(Elsevier, 2020)
This work includes the syntheses, molecular and electronic structure analyses of two novel secondary amide compounds 3-acetoxy-2-methyl-N-(2-methoxyphenyl)benzamide, 1 and 3-acetoxy-2-methyl-N-(3-methylphenyl)benzamide, ...
Phthalocyanines including 2-mercaptobenzimidazole analogs: Synthesis, spectroscopic characteristics, quantum-chemical studies on the relationship between electronic and antioxidant properties
(Elsevier, 2020)
In this study, peripherally tetra 2-mercaptobenzimidazole group substituted cobalt and indium phthalocyanine complexes (2 and 3) were prepared from 4-(benzo[d]imidazole-2-ylthio)phthalonitrile (1) for the first time. ...
New 1,3,4-thiadiazoles based on thiophene-2-carboxylic acid: Synthesis, characterization, and antimicrobial activities
(Elsevier, 2020)
Novel 1,3,4-thiadiazole derivatives were prepared by cyclization reaction of thiophene-2-carboxylic acid with N-arylthiosemicarbazides and POCl3. The antibacterial activities of the synthesized compounds were tested against ...
