Suzuki-Miyaura cross-coupling of arenediazonium salts with arylboronic acids catalyzed by a recyclable polymer-supported N-heterocyclic carbene-palladium catalyst

The Suzuki-Miyaura cross-coupling of arenediazonium salts with arylboronic acids catalyzed by a recyclable polymer-supported N-heterocyclic carbene-Pd complex catalyst has been achieved for the first time. The reaction was performed at room temperature under aerobic conditions to give biaryls in good to excellent yields in the absence of a base. The supported catalyst could be reused several times and still retained its high activity.
