Heck reaction of iodoarenes with methyl acrylate, catalyzed by cyclopalladated complexes of tertiary arylamines, was investigated in ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ( +BF - 4). The products can be isolated conveniently from the ionic liquid-catalyst system. The catalysts could be reused for more than 10 times still with satisfactory catalytic activity.
