A visible‐light‐mediated photoredoxMinisci‐typealkylation with ethers as the alkylating reagent is reported. User‐friendly LiBr has been found to be the key promoter for this radical coupling. The reaction exhibits broad functional group tolerance for both C2 and C4 couplings/alkylations of quinolines. Mechanistic studies suggest that the bromide additive could not only dramatically enhance the reaction
