Pd(II)-catalyzed selective sulfenylation of arene C–H bonds using N-arylthiobenzamides as thiolation reagent and oxidant
摘要:
The palladium-catalyzed direct sulfenylation of arenes with N-arylthiobenzamides was developed for the synthesis of aryl sulfides. Additional oxidant was not required for the catalytic cycle because N-arylthiobenzamide was used as both thiolation reagent and oxidant. The selective mono- or di-sulfenylation could be controlled by addition of the amount of N-arylthiobenzamide. Excellent functional group tolerance was observed and thioethers or dithioethers were obtained in good yields. (C) 2015 Elsevier Ltd. All rights reserved.

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

C–H bonds have been accomplished employing N-(arylthio)imides in combination with either Brønsted acid or Lewis acid, respectively. Notable features of the developed methodologies include excellent diversity, high functional group tolerance, wide substrate scope, and use of a single N–S reagent. Importantly, the developed hypothesis was also successfully extended to the amidation of C–H bonds. A plausible
