Reaktionsschritte
4′-Fluoro-biphenyl (0.03 mol) was added to 1 M AlCl3 in nitrobenzene (40 mL, 0.04 mol) with chilling in an ice bath. Acetyl chloride (0.06 mol) was added dropwise and the mixture stirred overnight at room temperature. The dark solution was poured into a mixture of crushed ice (150 mL), water (25 mL) and HCl (50 mL). The aqueous phase was separated and the nitrobenzene removed by steam distillation to give a dark low melting solid. The solid was recrystallised from aqueous methanol to give the title compound. δC (CDCl3, 62.9 MHz): 26.7, 115.9 (d, J 21.5), 127.1, 129.0 (d, J=7.8), 135.8, 136.0 (d, J 2.9), 144.7, 163.0 (d, J 248.0) and 197.8.
