For the synthesis of the ortho-anthraquinones 4-6 and 15 from the corresponding 2,6-dihydroxyanthracenes 1-3 and the 2-hydroxyanthracene 14, respectively, we performed a comparative study of the known reagents used for o-quinone preparation from phenols, namely phenylseleninic anhydride, potassium nitrosodisulfonate and tert-butyl hydroperoxide with the Mimoun complex as catalyst. Only phenylselenic anhydride gave the expected compounds in satisfying yields.
为了分别从相应的 2,6-二羟基蒽 1-3 和 2-羟基蒽 14 合成邻蒽醌 4-6 和 15,我们对用于从苯酚制备邻蒽醌的已知试剂进行了比较研究,这些试剂是苯硒酸酐、亚硝基二磺酸钾和叔丁基过氧化氢,并使用 Mimoun 复合物作为催化剂。只有苯硒酸酐能以令人满意的产率制备出预期的化合物。
