Abstract

Abstract: Negishi cross-coupling reactions between aryl-or benzylzinc halides and various aryl iodides smoothly occur in ionic liquids in the presence of the new ionic phosphine ligand 2. This solvent allows a facile work-up and rapid cross-coupling reactions at room temperature. Key words: palladium, catalysis, ionic liquids, zinc, cross-coupling
