Electrochemical Amide Bond Formation from Benzaldehydes and Amines: Oxidation by Cathodic-Generated Hydrogen Peroxide
The amide bondformation with benzaldehydes and amines by paired electrolysis is reported. 19 amide products were synthesized by this reaction. 1H NMR studies revealed that the corresponding hemiaminal intermediate is formed, which is then converted into the amide product. Control experiments showed that this electrochemical amidation occurs by anodic oxidation and cathodic generated H2O2.

cross-coupling of thiol derivatives with aryl bromides has now been established. This procedure provides access to simple and complex unsymmetrical diarylmethane molecules under mild reaction conditions with a broad functional group tolerance. The key steps of the reaction involve a silane-mediated halogen-atom transfer (XAT) and a subsequent intramolecular homolytic substitution (SH), forming C-centered
金属光氧化还原过程已成为 C−C 键形成的有效方法。现在已经建立了硫醇衍生物与芳基溴的 Ni-光氧化还原催化脱硫交叉偶联。该过程提供了在具有广泛的官能团耐受性的温和反应条件下获得简单和复杂的不对称二芳基甲烷分子的途径。反应的关键步骤涉及硅烷介导的卤素原子转移 (XAT) 和随后的分子内均裂取代 ( SH ),如机理研究所示,从各种硫醇衍生物形成以C为中心的自由基。这项研究为大量天然存在的硫醇的新转化铺平了道路。

performed using hydrogen gas and a metal supported on carbon, notably palladium (Pd/C). Though efficient, the need for a milder and operationally simple dehalogenation can arise. We found that the combination of Pd/C as catalyst and triethylsilane (TES) as hydrogen donor in THF resulted in a broadly applicable, easy to set up, and scalable debromination and deiodination. Optimization of the reaction showed
