실험 절차

A Schlenk tube was charged with CuI (19.5 mg, 0.102 mmol, 20 mol %), KCN (78 mg, 1.20 mmol), evacuated, backfilled with Ar. N,N′-Dimethylethylenediamine (21.5 μL, 0.202 mmol, 20 mol %), 5-bromo-m-xylene (136 μL, 1.00 mmol), and toluene (1.0 mL) were added under Ar. The Schlenk tube was sealed with a Teflon valve and the reaction mixture was stirred at 110° C. for 24 h. Dodecane (internal GC standard, 230 μL), ethyl acetate (2 mL), and 30% aq ammonia (1 mL) were added. A 0.1 mL sample of the supernatant solution was diluted with ethyl acetate (1 mL) and analyzed by GC to provide a 15% yield of 3,5-dimethylbenzonitrile.
