A new diphosphine, 6,6 -dimethoxy-2,2 -bis(di-2-pyridylphosphino)-1,1 -biphenyl (DPP), has been synthesized from commercially available 3-bromoanisole in four steps and fully characterized by 1H NMR, 31P NMR, 13C NMR and HRMS techniques. The palladium complex of the new ligand DPP provided excellent yields in Suzuki-Miyaura coupling reaction of aryl bromides with phenyl boronic acid, even in the presence of hindered and functional groups.
