    • General Procedure for the 1-Proline-Promoted Rosenmund-von Braun Reaction To a mixture of CuCN (2 mmol, L-proline (1 mmol, and anhyd DMF (3 mL) under argon, aryl bromide (1 mmol) was added at r.t. The mixture was stirred at 120°C for 45 h. After the resulting suspension was cooled to r.t, diluted with EtOAc (15 mL, and washed with H2O (3 x 4 mL, The organic phase was dried over Na2SO4, concentrated, and the residue was purified by flash chromatography on silica with EtOAc-hexane to yield the product.
