  Co-SAC催化甲醇和乙醇在偶氮键转移加氢中的应用：实验和理论研究

  摘要：

  使用甲醇和乙醇作为氢源的非极性键的转移氢化（TH）是一个巨大的挑战，而开发高效的3d金属基催化剂来完成此类反应是一个令人兴奋的探索领域。使用甲醇或乙醇将胺替代物选择性 TH 为其相应的伯胺是困难的，因为生产的主要产品是单/二烷基化胺。值得注意的是，偶氮键与胺的 TH 尚未有报道。在此，使用Co-SAC，使用乙醇和甲醇作为氢源，将包括市售染料在内的各种偶氮化合物有效地转移氢化为相应的伯胺。进行了几个对照实验来了解这一催化过程。哈米特研究表明，具有供电子取代基的底物更适合转移氢化。为了更深入地了解该机制，我们进行了 DFT 计算，揭示了醇脱氢和 -N N- 键氢化分别通过 β-氢化物消除和 Co-氢化物插入途径发生。

  Gold nanoparticles (Au-NPs) have been prepared using N-heterocyclic thiones (NHTs) as ligand stabilisers. These Au-NPs have been shown to be very stable, even in air, and have been characterized by a combination of several techniques (TEM, HR-TEM, STEM-HAADF, EDX, DLS, elemental analysis and 1H NMR). These nanoparticles are active in the catalytic reduction of nitroarenes to anilines.
