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)
Fe3O4@SiO2-SO3H as a recyclable heterogeneous nanomagnetic catalyst for the one-pot synthesis of substituted quinolines via Friedländer heteroannulation under solvent-free conditions
Volume 5, Issue 4, pp. 364-493, Serial No. 17 , October 2017, , Pages 484-493
Abstract
An efficient method has been developed for the Friedländer synthesis of substituted quinolines through a condensation reaction of 2-aminoaryl ketones with α-methylene ketones in the presence of a catalytic amount of nano Fe3O4@SiO2-SO3H under solvent-free conditions at 110 °C. The reactions ... Read More)
