The novel tetrasubstituted metal-free phthalocyanine (6) and metallophthalocyanines (7, 8) bearing four 14-membered tetraaza macrocycles moieties on peripheral positions have been synthesized by cyclotetramerization reaction ...
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 ...
Newly synthesized bentonite-histidine (Bent-His) micro-composite affinity sorbents for IgG adsorption
(Elsevier, 2007)
Bentonite has several advantages for use as a support, including its lack of toxicity, chemical reactivity and hydrophilicity allowing easy fixation of biomolecules. A new approach was developed to obtain an efficient and ...
