The rhodium‐catalyzed intermolecular directCH thiolation of arenes with aryl and alkyl disulfides was developed for the first time to provide a convenient route to aryl thioethers. This strategy is compatible with many different directing groups and exhibits excellent functional group tolerance. More significantly, mono‐ or dithiolation can be selectively achieved, thus providing a straightforward
The copper-mediated direct thiolation of carbazole derivatives with disulfides via C(sp2)–H bond cleavage was developed for synthesizing diaryl and alkyl aryl sulfides. This reaction exhibits wide tolerance toward various functional groups giving the products in good yields without any additives or ligands, and can be easily extended to the synthesis of thioethers carrying a benzo[h]quinolone, 2-phenylquinoline
铜介导的咔唑衍生物通过C(sp 2)–H键断裂与二硫键直接硫醇化反应,用于合成二芳基和烷基芳基硫醚。该反应显示出对各种官能团的宽容度,从而以高收率获得了产物,而没有任何添加剂或配体,并且可以容易地扩展到以令人满意的收率合成带有苯并[ h ]喹诺酮,2-苯基喹啉或吲哚部分的硫醚。
The Palladium-Catalyzed Intermolecular C–H Chalcogenation of Arenes
Palladium catalyzes the intermolecular chalcogenation of carbazole, 2-phenylpyridine, benzo[h]quinolone, and indole derivatives with disulfides and diselenides via selective C-H bond cleavage, providing a convenient route to thio and selenoethers.
