Mizoroki-Heck coupling reactions of arenediazonium tetrafluoroborate salts catalyzed by aluminium hydroxide-supported palladium nanoparticles

Mizoroki-Heck cross-couplings of arenediazonium tetrafluoroborate salts catalyzed by highly active aluminium hydroxide-supported palladium nanoparticles catalyst have been investigated for the first time. The reactions are performed at 25 degrees C in EtOH without any base and ligand to afford the corresponding coupling products in good to excellent yields under non-anhydrous and non-degassed conditions.
