Dimethyl Sulfoxide → 2-n-Octyloxytetracene-5,12-dione

Participants

Reaction Steps

20 g (72.4 mmol) of 2-fluorotetracene-5,12-dione, 94.3 g of 1-octanol, 30.01 g (217.2 mmol) of anhydrous potassium carbonate and 200 ml of DMSO are stirred at 100° for 20 hours. The reaction mixture is cooled, toluene/dilute hydrochloric acid are added, and the organic phase is separated off, washed twice with water, dried using sodium sulfate and evaporated. The residue is washed with pentane and recrystallized from cyclohexane.
