"Synthesis and Characterization of Copper Complexes derived from Dimedone derivatives"
Reactive methylene group at C2 position in dimedone plays an important role in the synthesis of a variety of organic ligands. Condensed compounds 3, 5, 7 were synthesized by reaction with dimedone and different aromatic aldehydes. Synthesized condensed compounds 3, 5 and 7 were on reaction with hydroxyl amine hydrochloride to yield oximes ligands 8, 9 and 10 respectively. The synthesized oxime ...

One-pot synthesis of Benzimidazole derivatives under microwave Irradiation and solvent-free condition
A simple, fast, efficient and environmentally friendly method for synthesis of benzimidazole and its 2-alkyl, aryl and heteroaryl substituted derivatives was developed using zeolite HY. Two component cyclolcondensation of 1,2-phenylenediamine (o-phenylenediamine) and commercially available carboxylic acids catalyzed by zeolite HY without any solvent, under microwave irradiation led to formation...
متن کاملAn efficient synthesis of pyridoxal oxime derivatives under microwave irradiation.
Quaternary salts of pyridoxal oxime have been synthesized by the quaternization of pyridoxal oxime with substituted phenacyl bromides using microwave heating. Microwave-assisted rapid synthesis was done both in solvent (acetone) and under solvent-free conditions. Good to excellent yields (58%-94%) were obtained in acetone in very short reaction times (3-5 min) as well as in the solvent-free pro...
