 Instead of hydrogen itself, however, a 2-alkyl-anthrahydroquinone, which is generated before from the corresponding 2-alkyl-anthraquinone by catalytic hydrogenation with palladium.
 Oxygen and the organic phase react under formation of the anthraquinone and hydrogen peroxide.
 Among other alkyl groups (R) ethyl- and tert.
 Butyl are used, e.g., 2-ethylanthraquinone.
