摘要：Water-soluble diol-functionalized imidazolium ionic liquid 1, prepared from 2,2-bis（1-methyl-methyl-imida- zolium）propane-l,3-diol bromide, potassium hydroxide, and malononitrile, was used as an efficient phosphine-free ligand for palladium-catalyzed arylation of aryl halides with acrylates in aqueous phase under mild conditions. It was found that the synergistic coordinating action of diol-functionalized imidazolium cation with CN-containing anion played the key role in improving the activity and stability of the catalyst.
