摘要：
1-(2-cyanoethyl)-3-(2-hydroxyethyl)-1H-imidazol-3-ium tetrafluoroborate (IL-2) in presence of PdCl2 was found to be an efficient and reusable, ligand-free, base-free catalytic system for Heck-coupling of activated and deactivated iodo- and bromoarenes with different olefins. Under microwave irradiation, it exhibited good efficiency in terms of activity, selectivity and recyclability for six consecutive runs without significant loss of activity.
