| Abstrakt: |
The demethylation of 2-methoxy-1-methylbenz[f]indolo-4,9-quinone with boron tribromide at -80°C gave 2-hydroxy-1-methylbenz[f]indole-4,9-quinone, which is converted quantitatively to the 3,4' dimer by the action of acids and bases and by heating. The state of the tautomeric equilibrium of the 2-hydroxybenzindolequinone in the crystalline state and in solutions was investigated by IR, PMR, and electronic spectroscopy. |
