  芳偶氮砜与硫醇和B2pin2的电化学硫代化和硼化

  摘要：

  已经开发了一种有效的各种不对称硫醚和芳基硼酸酯的电化学合成方法。台式稳定的芳基偶氮砜被用作在电化学条件下形成碳-杂原子键的自由基前体。此外，该方法的可扩展性是通过以克为单位对芳基偶氮砜与硫醇和B 2 pin 2进行电化学巯基化和硼化来评估的。该方案不仅避免了使用化学计量的氧化剂，金属催化剂，活化剂，甚至添加了碱，而且还表现出良好的官能团耐受性。

  This work describes a nickel-catalyzed Ullmann-type thiolation of aryl iodidesunder mild electrochemical conditions. The simple undivided cell with graphene/nickel foam electrode setups offers excellent substrate tolerance, affording aryl and alkyl sulfides in good chemical yields. Furthermore, the mechanism for this electrochemical cross-coupling reaction has been investigated by cyclic voltammetry

  Direct C-S bond coupling is an attractive way to construct aryl sulfur ether, a building block for a variety of biological active molecules. Herein, we disclose an effective model for regioselective thiolation of the aromatic C-H bond by thiol activation instead of arene activation. Strikingly, this method has been applied into anisole derivatives that are not available in the arene activation approach

  直接CS键偶联是构建芳基硫醚的一种有吸引力的方法，芳基硫醚是多种生物活性分子的基础。在这里，我们公开了通过硫醇活化而不是芳烃活化对芳香族CH键进行区域选择性硫醇化的有效模型。引人注目的是，该方法已被应用到芳烃活化方法中无法获得的苯甲醚衍生物中，从而形成具有高反应活性的单一硫醚异构体。

  An aerobic metal-free, visible-light-induced regioselective thiolation of phenols with thiophenols is reported. The cross-coupling protocol exhibits great functional group tolerance and high regioselectivity. Mechanistic studies reveal that the disulfide radical cation plays a crucial role in the visible-light catalysis of aerobic thiolation. Simply controlling the equivalent ratio of substrates enables

  A highly efficient palladium-catalyzed oxidative cross-coupling of arylhydrazines and arenethiols with molecular oxygen as the sole oxidant to afford unsymmetrical diaryl sulfides has been developed. The only byproducts are nitrogen and water. A broad range of functional groups, even the reactive iodides, are tolerated and thus offer the opportunity for further functionalization.
