  A method for the electrochemical synthesis of sulfinic esters by aerobic oxidative coupling of thiophenols and alcohols has been developed. Using electrons as the redox reagent and O2 in air as the oxygen source, the reactions proceeded smoothly at room temperature, even for a gram-scale preparation. No use of catalyst, clean redox reagent, green and abundant oxygen source, and mild reaction conditions

  已经开发了一种通过硫酚和醇的需氧氧化偶联电化学合成亚磺酸酯的方法。使用电子作为氧化还原试剂，并使用空气中的O 2作为氧气源，即使在进行克级制备时，反应在室温下也能顺利进行。无需使用催化剂，干净的氧化还原试剂，绿色和丰富的氧气源，以及温和的反应条件，使该策略变得环保。

  synthesis of cyclic sulfinates and sulfinamides based on intramolecular homolytic substitution (SHi) at the sulfur atom by aryl or alkyl radicals is described. Both alkyl and benzofused compounds can be accessed directly from easily prepared acyclic precursors. Enantiomerically enriched sulfur‐based heterocycles were formed through an SHi process with inversion of configuration at the sulfur atom. Cyclization

  描述了基于在硫原子上被芳基或烷基自由基的分子内均质取代（S H i）合成环状亚磺酸酯和亚磺酰胺的通用且有效的方法。烷基和苯并稠合的化合物都可以直接从容易制备的无环前体中获得。对映体富集的硫基杂环是通过S H i过程形成的，硫原子上的构型反转。前手性自由基的环化进行的立体化学结果各不相同，具体取决于传入自由基的大小。2-吡啶基和2-喹啉基会生成联芳基化合物，这是由于攻击芳基亚磺酸盐的邻位而不是亲硫取代引起的。

  electrophilic coupling partner, such as a benzylic, allylic or alkyl halide, an electron-poor arene, or a cyclic epoxide, to provide the corresponding sulfone products in good to excellent yields. The mild reaction conditions and use of commercially available reaction components allows the easy preparation of a broad range of sulfones featuring a variety of functional groups. The process obviates the need

  钯催化的氨基磺酰化工艺被用作一锅三组分砜合成中的关键步骤。该方法将芳基，杂芳基和烯基碘化物与磺酰基单元和亲电偶联片段结合。磺酰基单元以氨基磺酰胺的形式被递送，其然后用作掩蔽的亚磺酸盐。将亚磺酸盐原位合并用亲电偶合剂，例如苄基，烯丙基或烷基卤，贫电子芳烃或环状环氧化物，以良好至优异的产率提供相应的砜产物。温和的反应条件和可商购的反应组分的使用使得容易制备具有各种官能团的多种砜。该方法消除了使用硫醇原料和氧化操作的需要。

  The direct transformation of various thiols and simple alcohols with N-bromosuccinimide into sulfinic esters has been investigated by using different categories of base/acidic catalysts as well as co-solvents under varied reaction conditions. The reaction was found out to afford the sulfinic esters with high yields in the absence of catalysts, especially within the shorter time under the acceleration
