چکیده
|
The present paper introduces a simple and efficient method for the synthesis of substituted benzimidazoles by heterocyclization of different o-phenylenediamines and substituted aromatic carboxylic acid/aldehyde in the presence of zirconyl nitrate as catalyst in ethanol under reflux,which produced excellent yield of corresponding benzimidazoles in a short reaction time with reusability of catalyst. © 2013 pratapsinha b. gorepatil et al.
