Iron nanoparticles containing ppm quantities of palladium were effective for Suzuki-Miyaura coupling reactions of boronic acids, trifluoroborates, and N-methyliminodiacetic acid boronates with aryl and heteroaryl bromides and iodides in aqueous solutions containing the com. available surfactant TPGS-750-M. Treatment of FeCl3 (naturally containing 320 ppm Pd) with a phosphine ligand, particularly SPhos {dicyclohexyl(2′,6′-dimethoxy[1,1′-biphenyl]-2-yl)phosphine} or XPhos, in THF with a Grignard reagent in THF yielded Fe nanoparticles which were used as Suzuki-Miyaura coupling reaction catalysts with K3PO4 as base. The activity of the nanoparticles depended strongly on the iron source and the ligand used. The nanoparticles were recycled after extraction of product; for every two cycles, roughly 160 ppm Pd(OAc)2 was added to replace leached palladium.
