An efficient and one-pot green synthesis of 2-arylsubstituted benzimidazoles catalyzed by nano-Fe3O4@silica sulfuric acid as a recyclable nanomagnetic solid acid catalyst
Volume 8, Issue 1 , January 2020, , Pages 80-91
Abstract
An efficient and green protocol for the synthesis of 2-arylsubstituted benzimidazoles via a condensation reaction of aromatic aldehydes and 1,2-phenylenediamine using nano-Fe3O4@SiO2-SO3H as a solid acid catalyst in ethanol under reflux conditions has been described. The reactions are completed in short ... Read More)
