    • Synthesis of Ligands Ligands L1-L4 were prepared according to the reported procedures. 18,19 General Procedure A: Coupling of Aryl Iodides with Amines: A flask was charged with CuI (19 mg, 0.1 mmol, ligand (0.2 mmol, K3PO4 (424 mg, 2 mmol, and any remaining solid (amine and/or aryl halide, The flask was evacuated and backfilled with nitrogen. Aryl iodide (1 mmol, if liquid) and amine (1.5 mmol, if liquid, and DMF (1.0-1.5 mL) were added to the flask under a nitrogen atmosphere. The mixture was allowed to stir under the nitrogen atmosphere at the shown temperature for the indicated period of time see Table 2, After completion of the reaction, the mixture was diluted with EtOAc, the solution was filtered, and the inorganic salts were removed. The solvent in the filtrate was removed with the aid of a rotary evaporator, and the residue was purified by column chromatography on silica gel
