self-sustained productive Ni(I/III) cycle leading to a quantum yield Φ > 1; (ii) found that pyridinium iodide, formed in situ, serves as the dominant quencher for the excited state photocatalyst and a critical redox mediator to facilitate the formation of the active Ni(I) catalyst; and (iii) observed critical intermediates and determined the rate constants associated with their reactivity. Not only do the findings

Ni-catalyzed cross-couplings of aryl, benzyl, and alkyl thiols with aryl and heteroaryl iodides were accomplished in the presence of an Ir-photoredox catalyst. Highly chemoselective C-Scross-coupling was achieved versus competitive C-O and C-Ncross-couplings. This C-Scross-coupling method exhibits remarkable functional group tolerance, and the reactions can be carried out in the presence of molecular
