A nickel/visible light dual-catalyzed C—O bond coupling reaction between aryl/heteroaryl bromides and alcohols has been developed. Alkyl aryl ethers were efficiently synthesized by using organic photoredox-catalyst 2,4,5,6-tetra(9H-

carbazol-9-yl)isophthalonitrile (4CzIPN) or 2,4,5,6-tetrakis(diphenylamino)isophthalonitrile (4DPAIPN) in the presence of nickel(II) bromide 1,2-dimethoxyethane (NiBr2•DME), a ligand, and a base under 456 nm blue LED irradiation at room temperature. The reaction likely involves the oxidative addition of Ni(0) intermediate to aryl bromide, ligand exchange with the alcohol, oxidization of the resulting Ni(II) intermediate by the excited photoredox catalyst to form Ni(III) intermediate, and subsequent reductive elimination. This method exhibits broad substrate scope of alcohols, including benzyl alcohols, primary alcohols, and secondary alcohols, and with remarkable functional group tolerance.
