Microwave-assisted synthesis and antifungal activity of some new 1H-1,2,4-triazole derivatives
(Springer, 2008)
A number of 3-aryl-4-arylmethylideneamino-4,5-dihydro-1H-1,2,4-triazol-5- ones were synthesized by reaction of the corresponding aromatic aldehydes with 4-amino-3-aryl-1H-1,2,4-triazol-5-ones in anhydrous ethanol under ...
Binuclear transition metal complexes of a novel lateral ‒N-methylthiosemicarbazone through the central ethylene bridge: Synthesis, structural characterization and the response of ligand molecule to different solvent media
(Elsevier, 2008)
The condensation of 2,2?-(2,3-bis((1-formylnaphthalen-2-yloxy)methyl)but-2-ene-1,4-diy l)bis(oxy)di-1-naphthaldehyde with 4-methyl thiosemicarbazide gave a novel N-methylthiosemicarbazone and then the reaction of this ...
Ni(II), Cu(II), and Zn(II) complexes of tetradentate schiff base containing two thiadiazoles units: Structural, spectroscopic, magnetic properties, and molecular modeling studies
(Wiley, 2008)
Four new mononuclear metal complexes with a mononucleating Schiff base ligand containing two thiadiazoles units have been synthesized. The ligand and metal complexes were characterized by elemental analyses, IR, 1H, and ...
