The reaction of benzanthrone and aryl magnesium bromides produced 6-aryl-substituted benzanthrones in moderate to good yields. Similarly, 6-alkylaminobenzanthrones were selectively prepared by the reaction of benzanthrone and lithium alkylamides. In contrast, for the lithium arylamides, the arylamino groups were selectively introduced at the 4-position of the benzanthrone.
苯并蒽酮与芳基溴化镁的反应以中等至良好的产率产生了6-芳基取代的苯并蒽酮。类似地,通过苯并蒽醌和烷基酰胺锂的反应选择性地制备6-烷基氨基苯并蒽酮。相反,对于芳基锂锂,芳基氨基被选择性地引入苯并蒽醌的4-位。
