Abstract: A new diphospine, 6,6′-dimethoxy-2,2′-bis(di-N-carbazolylphosphino)-1,1′-biphenyl (3), has been synthesized from commercially available 3-bromoanisole in five steps and fully characterized by 1H NMR, 31P NMR, 13C NMR, and high-resolution mass spectrometry. The palladium complex with the new ligand 3 provided excellent yields in Suzuki coupling reaction of aryl bromides and phenylo boric acid, even in the presence of hindered and functional groups.

Key words: Suzuki cross-coupling, diphosphine ligand, N-carbazolyl, palladium, aryl bromide, phenylo boric acid
