A Suzuki-Miyaura cross-coupling of arenediazonium salts with arylboronic acids using a recyclable polymer-supported N-heterocyclic carbene-Pd complex catalyst was performed at room temperature under aerobic conditions to give biaryls in very good yields in the absence of a base. The supported catalyst could be reused several times and still retained its high activity.
