Fe(HSO4)3-Catalyzed Direct Conversion of Aldehydes into Nitriles Using Hydroxylamine Hydrochloride
Due to the importance and various applications of nitriles especially in medicinal productions, a new method for conversion of aldehydes to nitriles has been presented. Several nitrile-containing aromatic compounds were synthesized through the treatment of various aldehydes and hydroxylamine hydrochloride as nucleophile in the presence of ferric hydrogen sulfate as a heterogeneous, efficient, a...
متن کاملOne-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 کاملOne-pot synthesis of aromatic nitriles from aldehydes using magnetic material separated from coal fly ash
An efficient and simple procedure for the direct synthesis of Aromatic Nitriles from Aldehydes, Hydroxylamine Hydrochloride is described using magnetic material separated from coal fly ash. Coal fly ash is a waste material generated in huge amount by burning of coal for the generation of electricity in thermal power station. It contains SiO2, Al2O3 and magnetic material in significant amounts, ...
