Abstrakt: The diazotization of 3-substituted 2-amino-1H-phenalen-1-ones (substituents=Cl, Br, PhS, or OH) gave 2-diazo-1H-phenalene-1,3(2H)-dione. It is most probable that the reaction involves the intramolecular rearrangement of a transient diazohydroxide intermediate and the consequent elimination of the substituent at the 3-position.
