An efficient and chemodivergent palladium-catalyzed thiolation (C-S) and imidation (C-N) of directing group-assisted C-H bonds have been accomplished employing N-(arylthio)imides in combination with either Br?nsted 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 mechanistic pathway was proposed based on the preliminary mechanistic study.

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.

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.

A catalytic variant of the direct thiolation of arenes, bearing directing groups, with disulfides or thiols has been developed under palladium and copper co-catalysis. Both sulfenyl moieties of the disulfide could be incorporated into the thiolated produc

The rhodium-catalyzed intermolecular direct C-H 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 way for selective preparation of aryl thioethers and dithioethers.
