An efficient palladium-catalyzed process has been developed for Negishi coupling of secondary alkylzinc halides and sterically and electronically demanding aryl bromides and activated aryl chlorides. The palladium catalyst composed of a new biaryldialkylphosphine ligand, CPhos, effectively promotes the reductive elimination step relative to the undesired β-hydride elimination pathway. The general substrate scope and excellent ratio of the desired secondary to the undesired primary coupling product make this method a powerful and reliable tool for C(sp3)-C(sp2) bond formation.
