Participants

Reaction Steps

Pyrocatechol (99.0 g; 0.9 mole) was dissolved in methanol (2.5 l), then morpholine (360 ml; 4.1 mole) and cupric acetate (9.0 g) were added. Air was bubbled through the reaction solution for about 9 hours. The mixture was cooled and filtered; the solid was washed with methanol (1.5 l) and air dried. The yield was 150.3 g (60%).
