Aluminum sec-butoxide → 2,9-Difluoropentacene

Participants

Reaction Conditions

Reaction Steps

To a mixture of 0.5 grams of 2,9-difluoropentacene-5,7,12,14-tetrone and 20 mL of cyclohexanol in a flask was added 3.640 grams of aluminum tri(sec-butoxide). The mixture was heated at 100° C. for approximately 12 hours and a blue solid deposited on the sides of the flask. The reaction mixture was centrifuged and the blue solid residue was washed with cyclohexanol, centrifuged twice, and then washed with acetone and collected by filtration. This solid was washed with 50% concentrated HCl and the resulting mixture was centrifuged to give a blue solid. This solid was washed with THF and collected by centrifugation to give 2,9-difluoropentacene.
