4-Nitro-2',3',4',5',6'-pentafluorobiphenyl → 2',3',4',5',6'-Pentafluoro[1,1'-biphenyl]-4-ylamine

Participants

Reaction Steps

4-Nitro-2′,3′,4′,5′,6′-pentafluorobiphenyl (10 g, 0.0345 mol) was dissolved in absolute ethanol (750 mL) and stirred under a hydrogen atmosphere (1 atm.) over Pd/C (0.3 g) until absorption of hydrogen ceased. The solution was filtered and the solvent was removed. The crude product was purified by column chromatography to give 4-amino-2′,3′,4′,5′,6′-pentafluorobiphenyl as a white powder (8.0 g, 89% yield).
