A Novel Graphene-Supported Palladium Catalyst for Suzuki-Miyaura Coupling of Less Reactive Heteroaryl Halides in Water

An efficient reduced graphene oxide‐supported heterogenized palladium complex with pyrene‐tagged ketoiminato ligand has been developed and used for cross‐coupling of less reactive heteroaryl halides in water. Desirable catalytic activity was observed with high (up to 98%) conversion of the less reactive reactants under relatively mild conditions. The efficiency and green nature of the catalyst were confirmed without significant loss of activity.
