Notwithstanding some progress in nickel-catalyzed etherification of alkanols and arylhalides, the ability of such a Ni-catalyzed transformation employing phenols to diaryl ethers is unsuccessful due to phenolates with much lower reduction potentials, which suppress the oxidation of nickel(II) intermediates into requisite Ni(III) species. We herein report visible-light-initiated, nickel-catalyzed O-arylation of phenols with arylhalides using t-BuNH(i-Pr) as the base and thioxanthen-9-one as the photosensitizer under visible light. This photocoupling exhibits a broad substrate scope.

A practical and mild strategy has been developed for the selective O-arylation on C-6 substituted pyridin- 2-ones with a series of arylboronic acids, using Cu(OTf)2 as the catalyst, DABCO as the ligand, Et3N as the base, and K2HPO4 as the additive. This method affords O-arylated pyridin-2-ones with good selectivity and yields. Copyright
