2,3,4,5,6-Pentafluorobenzophenone → HCID 22481417, compound

Participants

Reaction Steps

Pentafluorobenzophenone (10.4 g) was dissolved in 250 ml of benzene/isopropanol (3.5:1). The solution was purged with nitrogen and irradiated for 6 hours with a Hanovia 450-watt Hg-arc lamp. The solvent was removed using a vacuum evaporator at a temperature less than 40° C. The crystallized product was washed twice with 25 ml of n-pentane. The slurry was centrifuged and n-pentane was decanted. The product was spread on a watch glass and air dried. Recovery of 2,3,4,5,6,2',3',4',5',6'-decafluorobenzopinacol was 9.1 g or 87.5%.
