A nickel-catalyzed C–SPy bond activation reactions to produce a variety of thioethers has been developed. The reaction is promoted by a user-friendly, inexpensive, air and moisture-stable Ni precatalyst. Various aryl 2-pyridyl thioethers and a wide range of alkyl and aryl thiols substrates were tolerated in this process which afforded products in moderate to excellent yields.

CovalentOrganicFrameworks (COFs) have recently emerged as light‐harvesting devices, as well as elegant heterogeneous catalysts. The combination of these two properties into a dual catalyst has not yet been explored. We report a new photosensitive triazine‐based COF, decorated with single Ni sites to form a dual catalyst. This crystalline and highly porous catalyst shows excellent catalytic performance

Disclosed is a mild, scalable, visible-light-promotedcross-couplingreaction between thiols and aryl halides for the construction of C-S bonds in the absence of both transition metal and photoredox catalysts. The scope of aryl halides and thiol partners includes over 60 examples and therefore provides an entry point into various aryl thioether building blocks of pharmaceutical interest. Furthermore

In one aspect, the invention provides a method of promoting a carbon-sulfur bond forming reaction. In certain embodiments, the reaction comprises cross-coupling of a(n) (hetero)aryl halide with a thiol to form the carbon-sulfur bond, wherein the method is promoted by light irradiation in the absence of a photocatalyst. In other embodiments, the cross-coupling reaction can be promoted through visible light irradiation, including sunlight.

Metal–organic frameworks (MOFs) have been extensively used for single‐site catalysis and lightharvesting, but their application in multicomponent photocatalysis is unexplored. We report here the successful incorporation of an IrIII photoredox catalyst and a NiII cross‐couplingcatalyst into a stable Zr12 MOF, Zr12‐Ir‐Ni, to efficiently catalyze C−S bond formation between various aryl iodides and thiols
