실험 절차

Magnesium (36 g, 1.5 mmol), iodine (a few Crystals) and THF (1 L) were heated under nitrogen, with stirring, at reflux for 15 min. The mixture was cooled to 20° C., stirring stopped, and 1,2-dibromoethane (2.5 ml) added. After an exothermic reaction was observed (a few min) stirring was restarted which was accompanied by a rise in temperature to 35° C. The mixture was cooled to 20° C. and 4-bromoanisole slowly added over 1 h at 14°-18° C. with cooling. Stirring was continued for 10 min after the addition was complete.
