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 کاملFacile Synthesis of Hydantoin Derivatives under Microwave Irradiation
In recent years, microwave irradiation using commercial domestic ovens for the optimization and acceleration of organic reactions has rapidly increased1−2.It has been reported that a variety of reactions such as Dielsalder , ene, Claisen reactions , Fischer cyclization, synthesis of heterocycles , hydrolysis of esters , hydrogenation, deprotection of benzyl ester, deacetylation of diacetates, o...
متن کاملOne-pot synthesis of disperse dyes under microwave irradiation: dyebath reuse in dyeing of polyester fabrics.
A series of 4-hydroxyphenylazopyrazolopyrimidine disperse dyes were prepared via one-pot reactions of p-hydroxyphenylhydrazone, hydrazine hydrate, and acetylacetone or enaminones using microwave irradiation as an energy source. Structural assignments of the dyes were confirmed by X-ray crystallographic structure determination. Instead of discharging the dyebath after each dyeing cycle, the resi...
