Abstract

A discovery that inexpensive elemental bromine can act as a potent Lewis acid catalyst is disclosed. Under the catalysis of only 2 mol% of Br 2 , indoles reacted rapidly with carbonyl compounds to give bis(indolyl)methanes with extremely high efficiency and wide substrate scope. Moreover, a Br 2 -catalyzed aqueous-phase reaction is also presented to further demonstrate the power of this novel catalyst.
