The utilization aryl di- and trithiosulfonates nickel-catalyzed reductive coupling with halides has been unexplored. Herein, we unprecedentedly describe PPh3 Zn-collaborative reduction-induced nickel-catalytic selective C–S di/trithiosulfonates access sulfides over common disulfides or trisulfides. Diverse mechanistic studies indicate that the key design such reaction could be attributed employment MgCl2, which collaborate Zn for improved reduction potential enables cleavage PhSO2(S)naryl (n = 2, 3) electrophilic sulfur species sulfuration controllable fashion.

The direct cross-couplings of aryl nonaflates with bromides could be successfully accomplished by utilizing nickel as the catalyst, magnesium metal mediator, and lithium chloride additive. reactions proceeded efficiently in THF at room temperature to produce desired biaryls moderate good yields, showing both a reasonable substrate scope functional group tolerance. Additionally, an equally performance realized when reaction was subjected scale-up synthesis. Preliminary study suggested that presumably proceeds through situ formation arylmagnesium reagent key intermediate.

A palladium-catalyzed decarboxylative cross-coupling of zinc polyfluorobenzoates with aryl fluorosulfates, which proceeded efficiently via C-O bond cleavage to afford the corresponding polyfluorinated biaryls in moderate-to-good yields, was developed. The reactions exhibited both good substrate scope and broad functional group compatibility, it could be scaled-up easily. synthetic simplicity practicability reaction further demonstrated by one-pot manipulation directly mixing polyfluorobenzoic acid Zn(OH)2 coexistence fluorosulfate a palladium catalyst one flask. Further studies showed that is more robust than other halides pseudohalides as arylating reagent, polyfluorobenzoate effective polyfluoroarylating agent their magnesium potassium counterparts.

An efficient dehydroxythiolation between alcohols and disulfides using the widely abundant cheapest iron as a reaction mediator was developed. The one-pot thiolation proceeded effectively via C-O bond activation with aid of cyanuric chloride (TCT) hydroxyl-activating agent to give corresponding thioethers in modest excellent yields, displaying both wide substrate scope (applicable benzyl alcohol, allyl primary alkyl alcohol) good functional group tolerance. In addition, diselenide also proven be an appropriate for protocol, could subjected scale-up synthesis. Preliminary mechanistic examination revealed that transiently formed TCT-derived ether A, which is generated situ TCT possibly serves pivotal intermediate cross-electrophile thioetherification.
