We have proven that pyridine–boryl complexes can be used as superelectron donors to promote the coupling of thiols and aromatic halides through a SRN1 mechanism. The reaction is efficient for a broad substrate scope, tolerating heterocycles including pyridines, enolizable or reducible functional groups. The method has been applied to intermediates in drug synthesis as well as interesting functionalized
我们已经证明,吡啶-硼基复合物可用作超电子供体,通过 S RN 1 机制促进硫醇和芳族卤化物的偶联。该反应适用于广泛的底物范围,可耐受杂环,包括吡啶、可烯醇化或可还原的官能团。该方法已通过受控和连续的分子内电子转移过程应用于药物合成中的中间体以及有趣的功能化聚硫醚。

Redox-active benzimidazolium sulfonamides as thiolating reagents have been developed for reductive C–S bond coupling. The IMDN-SO2R reagent provides a bench-stable cationic precursor to generate a portfolio of highly active N–S intermediates, which can be successfully applied in cross-electrophilic coupling with various organic halides. The employment of an electrophilic sulfur source solved the problem
已开发出具有氧化还原活性的苯并咪唑磺酰胺作为硫醇化试剂用于还原 C-S 键偶联。IMDN-SO 2 R 试剂提供了一种稳定的阳离子前体,可生成一系列高活性 N-S 中间体,可成功应用于与各种有机卤化物的交叉亲电偶联。采用亲电硫源解决了催化剂失活问题,避免了硫醇的异味,具有条件实用、底物范围广、耐受性好等特点。
Rhodium-catalyzed odorless synthesis of diaryl sulfides from borylarenes and S-aryl thiosulfonates
Various diarylsulfides, including heteroaryl- and nitrogen-containing sulfides, have been efficiently prepared by rhodium-catalyzed odorless deborylative arylthiolation of organoborons with S-aryl thiosulfonates. The ready availability of starting materials and further transformation of sulfides have rendered a diverse range of organosulfur compounds easily accessible.
