An efficient protocol for the Suzuki reaction catalyzed by Pd/C has been developed in a green sovent. This method is able to prepare a variety of biaryls in high yields. In the presence of 1-butyl-3-methylimidazolium bis[(trifluoro-methyl)sulfonyl]imide, the cross-coupling reaction of aryl bromides with arylboronic acids proceed smoothly in PEG400 aqueous at 45℃. The catalyst could be recycled four times without loss of activity.

Key words: Pd/C, Suzuki reaction, biphenyls, ionic liquid
