Abstract: The direct cross-couplings of diaryl sulfoxides with aryl bromides via C−S bond cleavage could be readily accomplished using nickel(II) as the catalyst, 1,2-bis(diphenylphosphino)ethane (dppe) as the ligand, and magnesium turnings as the reducing metal in THF, leading to the corresponding biaryls in moderate to good yields. The reaction exhibited a broad substrate scope and could be applied to a gram-scale synthesis. The “one-pot” reaction, which avoids the utility of presynthesized and moisture-labile organometallic compounds, is operationally simple and step-economic.
