Procedure

A screw cap test tube was charged with n-heptanol (283 μL, 2.00 mmol), 3,5-dimethyliodobenzene (144 μL, 1.00 mmol), CuI (19.0 mg, 0.100 mmol), ligand (0.200 mmol), Cs2CO3 (977 mg, 3.00 mmol) and toluene (1 mL). The test tube was sealed with a screw cap. The reaction mixture was stirred magnetically and heated at 110° C. for 39 hours. The reaction mixture was allowed to reach room temperature. Dodecane (227 μL, 1.00 mmol; internal standard) was added and a GC sample was filtered through Celite and eluted with CH2Cl2. The yield of the desired product was determined using GC analysis; the results are tabulated below.
