  摘要：

  芳胺是在商业上和合成上有用的化合物，具有广泛的应用。传统上，它们的制备是通过金属催化的C-N与芳基卤化物的偶联反应实现的。在这项工作中，使用甲酸铵作为胺化剂，从苯酚中制备了17种不同的二芳基胺。酚类化合物由于可从木质素中获得，因此是更理想的原料，使其成为芳基卤化物的有价值的生物可再生替代品。发现甲酸铵是氨的方便替代物和酚的有用胺化试剂。获得二芳基胺产物的产率高至优异，而仅水和CO 2作为转化的副产物产生。

  palladium nanoparticle catalyst (Pd/TiO2) gave the desired diarylamines, the catalytic activity was inferior to that of Au–Pd/TiO2. Moreover, the activity of Au–Pd/TiO2 was superior to that of a physical mixture of Au/TiO2 and Pd/TiO2. The present Au–Pd/TiO2-catalyzed transformation of cyclohexylamines proceeds through complex pathways comprising amine dehydrogenation, imine disproportionation, and condensation

  二芳胺是一类重要的广泛使用的化学品，开发其合成的多种方法非常重要。在此，我们成功开发了通过无受体脱氢芳构化合成二芳基胺的新型多功能催化程序。在金-钯合金纳米粒子催化剂（Au-Pd/TiO 2 ）存在下，可以从环己胺开始合成各种对称取代的二芳基胺。观察到的Au-Pd/TiO 2催化本质上是非均相的，并且Au-Pd/TiO 2可以重复使用多次而不会严重损失催化性能。这种转化不需要氧化剂，并产生分子氢（相对于环己胺而言是三当量）和氨作为副产物。这些特征凸显了当前转型的环境友好性。此外，在Au-Pd/TiO 2存在下，可以从各种底物组合开始成功地合成各种结构多样的不对称取代的二芳基胺，例如（i）苯胺和环己酮，（ii）环己胺和环己酮，以及（iii） ）硝基苯和环己醇。详细研究了催化剂的作用和环己胺转化的反应途径。催化性能很大程度上受催化剂性质的影响。在负载型金纳米粒子催化剂(Au/TiO 2 )的存在下，几乎不能产生所需的二芳基胺。
