Procedure

A Sclenk tube was charged with CuI (9.6 mg, 0.0504 mmol, 5.0 mol %), sodium iodide (fine powder, dried, 300 mg, 2.00 mmol), evacuated and backfilled with argon. trans-N,N′-Dimethyl-1,2-cyclohexanediamine (16 μL, 0.10 mmol, 10 mol %), 5-bromo-m-xylene (136 μL, 1.00 mmol), and solvent (1.0 μL) were added under argon. The Schlenk tube was sealed with a Teflon valve and the reaction mixture was stirred at 110° C. for 23 h. The resulting suspension was allowed to reach room temperature. Ethyl acetate (2 mL) and dodecane (internal GC standard, 230 μL) were added to the reaction mixture. A 50 μL sample of the supernatant solution was diluted with ethyl acetate (1 mL) and analyzed by GC. The results are tabulated below.
