Abstract
Abstract A rhodium terpyridine complex catalyzed transfer hydrogenation of nitroarenes to anilines with i ‐PrOH as hydrogen source and water as solvent has been developed. The catalytic system can work at a substrate/catalyst (S/C) ratio of 2000, with a turnover frequency (TOF) up to 3360 h −1 , which represents one of the most active catalytic transfer hydrogenation systems for nitroarene reduction. The catalytic system is operationally simple and the protocol could be scaled up to 20 gram scale. The water‐soluble catalyst bearing a carboxyl group could be recycled 15 times without significant loss of activity.
