TRANSFORMATIONS OF POLYCYCLIC KETONES: XX. ELECTROPHILIC SUBSTITUTION REACTIONS OF 3-AMINOPHENALENONE

The corresponding 2-substituted cmpounds are formed during the nitration, bromination, and azo coupling of 3-aminophenalenone.In sulfuric acid 3-aminophenalenone is protonated first at the carbonyl oxygen atom, and with increase in the concentration of the acid a second proton adds to the amino group.
