Reaktionsschritte

Zinc chloride (27.4 g, 201 mmol), diethylamine (15.6 mL, 151 mmol) and t-butanol (14.4 mL, 151 mmol) were combined in benzene (151 mL) at room temperature under a nitrogen atmosphere and stirred for 2 h. 1-(4-chloro-3-nitrophenyl)ethanone (30.1 g, 151 mmol) and 2-bromo-1-(4-chloro-3-nitrophenyl)ethanone (28 g, 101 mmol) were added. The mixture was stirred vigorously for 20 h, and the solid product was collected by filteration and rinsed with benzene, water, methanol, and dichloromethane. The solid was dried in a vacuum oven.
