Abstract

Abstract A unique combination of steric and electronic properties appears to determine the effectiveness of phosphanyl-substituted biphenyls as ligands in palladium-catalyzed aminations and Suzuki coupling of aryl chlorides at room temperature [Eq.(1)]. The oxidative addition step is greatly accelerated, and transmetalation (or Pd− N bond formation) and reductive elimination processes are facilitated. Use of these ligands allows for Suzuki ...
