卤代蒽醌和不同的胺类在铜催化剂存在下生成氨基蒽醌,这个反应是大家所熟知的,就是所谓的乌尔曼(Ullmann)氏氨化作用,它广泛应用于蒽醌中间体和染料的制备。我们近来发现了α-取代蒽醌与烷基胺类之间由金属促进的一种新的氨化反应。有些烷氨基蒽醌可以在温和的条件下以良好收率方便地合成出来。 Halogenated anthraquinones and different amines produce aminoanthraquinones in the presence of copper catalysts. This reaction is well-known and is known as Ullmann’s amination, which is widely used in anthraquinone intermediates and Preparation of dyes. We have recently discovered a new amination reaction promoted by metals between α-substituted anthraquinones and alkylamines. Some alkylamino anthraquinones are conveniently synthesized in good yields in mild conditions.
