Highly efficient, recyclable Pd(II) catalysts with bisimidazole ligands for the Heck reaction in ionic liquids.
[reaction: see text] New Pd(II) complexes with bisimidazole ligands were prepared and proved to be effective catalysts for the Heck reaction under phosphine-free conditions using ionic liquids as solvents. This system could be recycled five times without any loss of catalytic activity.
