The oxidation of 4-substituted catechols including DOPA with <I>o</I>-chloranil or cerium(IV) sulfate to give the corresponding <I>o</I>-benzoquinones was examined. The trapping of <I>o</I>-benzoquinones with <I>o</I>-phenylenediamine immediately after oxidation was successfully used to isolate 2-substituted phenazines, the substituents being –CH<SUB>3</SUB>, –CH(CH<SUB>3</SUB>)<SUB>2</SUB>, –(CH<SUB>2</SUB>)<SUB>2</SUB>CO<SUB>2</SUB>H, –(CH<SUB>2</SUB>)<SUB>2</SUB>CO<SUB>2</SUB>CH<SUB>3</SUB>, –CH=CHCO<SUB>2</SUB>H, –CH=CHCO<SUB>2</SUB>CH<SUB>3</SUB>, –(CH<SUB>2</SUB>)<SUB>2</SUB>NHCOC<SUB>6</SUB>H<SUB>5</SUB>, and –CH<SUB>2</SUB>CH(NHCOC<SUB>6</SUB>H<SUB>5</SUB>)CO<SUB>2</SUB>CH<SUB>3</SUB>. Dopaquinone was identified in a protected form.
