NaHSO 4 - SiO 2 promoted synthesis of Benzimidazole derivatives
a library of benzimidazole derivatives have been prepared through the reaction of o-phenylenediamine and aldehydes in the presence of catalytic amount of silica supported sodium hydrogen sulphate (NaHSO4-SiO2) under refluxing in ethanol solvent to obtained excellent yields. This method is simple, convenient, environmental friendly, reusable, efficient and practical.
متن کاملDowex-50W-Promoted Synthesis of Oxazoline, Imidazoline and Thiazoline Derivatives
Dowex-50W-hyodrgen ion exchange resin was used as a reusable catalyst for the synthesis of oxazoline, imidazoline and thiazoline derivatives through condensation reaction between arylnitriles and 2-aminoalcohol, ethylenediamine or 2-aminoethanthiol. This process provides several advantages such as excellent yields of the products, simple operation, convenient separation and inexpensive and recy...
متن کامل"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 ...
