Abstract

A clean and efficient method for the synthesis of bis(indolyl)methane derivatives with antimony zwitterionic-typemolten salt-catalyzed (IBS) as the catalyst under solvent-free conditions is described. This method provides several advantages, such as simple work-up procedure, neutral conditions using a cheap, non-toxic, environment friendly solvent, and high yields.
