Under nitrogen atmosphere, a Schlenk tube was sequentially charged with cyclic diaryliodonium salt 9 (0.15 mmol), CuSCN (1.2 mg, 10.0 mol%), L6 (12.5 mg, 15.0 mol%), CaO (11 mg, 0.2 mmol, 2.0 equiv) and dichloromethane (0.1 M). Then the appropriate amine 10 (0.10 mmol) was added and stirred for the time indicated in the experimental procedures. The reaction was filtered through a plug of celite with ethyl acetate (10 mL). The filtrate was concentrated under reduced pressure, and the residue was purified by column chromatography on silica gel to deliver the corresponding product 11.
