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, S and the solid product was collected by filtration and rinsed with benzene, water, methanol, and dichloromethane. The solid was dried in a vacuum oven.
