An efficient catalytic system for the ligand-free SuzukiâMiyaura reaction in water at room temperature is disclosed, promoted by Stilbazo (stilbene-4,4â²-bis[(1-azo)-3,4-dihydroxybenzene]-2,2â²-disulfonic acid diammonium salt). The desired carbonâcarbon bond formation proceeded well under mild conditions with high efficiency and good functional group tolerance.
