Abstract

An efficient synthesis of bis(indolyl)methanes through Fe ^III-catalyzed electrophilic substitution reactions of indoles with various aldehydes in ionic liquid is described. It was found that the ionic liquids involving FeCl₃·6H₂O were the most efficient catalytic systems, and could be simply recycled without significant loss of activity.
