• bis(indolyl)methanes
• solvent-free conditions
• Wells-Dawson heteropolyacid
• electrophilic substitution
• diphosphooctadecatungstic acid
• H6P2W18O62

Bis(indolyl)methanes have been synthesized in excellent yields in the presence of a catalytic amount of Wells-Dawson type heteropolyacid under solvent-free conditions. The catalyst is recycled and reused several times.
