Abstract
PURPOSE: To prepare the title cpds. by oxidation of acenaphthenes with molecular oxygen in the presence of a heavy metal cpd, bromine cpd, or the like as a catalyst, an accelerator and a cocatalyst such as a tert-amine, followed by treatment of the resulting cpds. with a peracid or hypohalogenous acid salt.
