Abstract

Abstract Reaction of 2, 5-dihydroxy-1, 4-benzoquinone with pyridine, 3-picoline and acridine in acetic anhydride lead to the preparation of 3-(4-pyridyl)-1, 2, 4, 5-benzenetetrol tetraacetate, 3-[4-(3-methylpyridyl)]-1, 2, 4, 5-benzenetetrol tetraacetate and 3-(9-acridyl)-1, 2, 4, 5-benzenetetrol tetraacetate, respectively. Moreover, it was possible to isolate the complex derived from the corresponding amines and the quinone. The reaction conditions ...
