A highly effective C?O coupling reaction of (hetero)aryl electrophiles with primary and secondary alcohols is reported. Catalyzed by a NiII-aryl complex under long-wave UV (390–395 nm) irradiation in the presence of a soluble amine base without any additional photosensitizer, the reaction enables the etherification of aryl bromides and aryl chlorides as well as sulfonates with a wide range of primary and secondary aliphatic alcohols, affording synthetically important ethers. Intramolecular C?O coupling is also possible. The reaction appears to proceed via a NiI–NiIII catalytic cycle.

An enantioselective intramolecular O-arylation was achieved through desymmetrization with Pd-catalyzed coupling reactions. The intramolecular asymmetric aryl C-O coupling reactions of 2-(2-haloaryl)propane-1,3-diols led to the enantioselective formation o

Carbonylative cyclization of iodoarenes and iodoalkenes containing a proximal enolate precursor can selectively provide either cyclic ketones or lactones in the presence of Ni or Cu catalysts via trapping of putative acylmetal derivatives with C- or O-enolates, respectively; the ring size and regioselectivity of the reaction may be predicted based on two generalizations derived from the recently developed corresponding Pd-catalyzed reaction.
