文摘

The synthesis of bis(indolyl)methanes catalyzed by graphene oxide is developed. Graphene oxide could be used as solid acids to catalyze Friedel–Crafts reaction. The reaction was performing in water and the catalyst could be reused ten times. This methodology has a broad substrate scope and good to excellent yields.
