The reaction of 1-aminoanthraquinone with primary aliphatic amines in the presence of cobalt(II) chloride under atmospheric oxygen preferentially gave the corresponding 1-amino-4-(alkylamino)anthraquinones. The reaction did not proceed with aqueous ammonia, bidentate amines, secondary aliphatic amines, and primary arylamines. While, with alicyclic amines the reaction mainly afforded 1-amino-2,4-bi
1-氨基蒽醌与脂肪族伯胺在氯化钴 (II) 存在下在大气氧气下反应优先得到相应的 1-氨基-4-(烷基氨基)蒽醌。该反应不使用氨水、二齿胺、仲脂肪胺和伯芳胺进行。同时,与脂环胺反应主要提供 1-氨基-2,4-双(烷基氨基)蒽醌。
