O-Phenylenediamine → 2,3-Bis(4-fluorophenyl)quinoxaline

참여 물질

반응 단계

First, 3.71 g of 4,4′-difluorobenzil and 1.71 g of o-phenylenediamine were stirred on heating in a solvent (200 mL of chloroform) for 6 hours. The reaction solution was cooled to room temperature, washed with HCl (1N) and a saturated aqueous solution of sodium chloride, and dried with magnesium sulfate. The solvent was removed to obtain a ligand HFdpq (2,3-bis(4-fluorophenyl)quinoxaline) (pale yellow powder, yield: 99%).
