Abstract

Abstract New procedures were developed for preparing substituted 2, 3- dicarboxyanthraquinones by acylation of arenes with pyromellitic anhydride, followed by intramolecular cyclization of the products. The 2, 3-dicarboxyanthraquinones prepared were further modified by oxidation, sulfonation, nitration, and reduction.
