Synthesis of azo-linked diindolyl methanes using Fe3+-montmorillonite K10 under solvent-free condition

Abstract

Efficient nucleophilic addition reactions of indole derivatives with various azo-linked aldehydes were carried out using Fe3+-montmorillonite K10 under solvent-free conditions to afford the corresponding diindolylmethanes in short reaction times and excellent yields.
