Abstract

Green, mild and efficient electrophilic substitution reactions of indoles with various aldehydes were carried out using solid superacid SO4 2-/TiO2 as recyclable catalyst, which afforded the corresponding bis(indolyl)methanes in excellent yields.

Keywords: synthesis, recycle, bis(indolyl)methanes, solvent-free, indoles, solid superacid
