  Palladium-Catalyzed Direct Arylation of Thiophenes Bearing SO₂R Substituents

  摘要：

  The palladium-catalyzed direct arylation of SO2R-substituted thiophene derivatives was found to proceed regioselectively at CS and in high yields using a variety of aryl bromides and as low as 0.5-0.1 mol % of phosphine-free Pd(OAc)(2) as the catalyst. For these reactions, sulfonyls, sulfonamides, or even a sulfonic ester as the thiophene substituents were successfully employed.
