Photocatalytic multicomponent reactions are at the forefront of organic synthesis. In recent years, the dicarbofunctionalization of olefins has received significant attention, with nickel serving as a key transition metal catalyst under photochemical conditions. However, achieving regioselective 1,4-alkylarylation of dienes with alkyl and aryl bromides remains challenging. In this work, we present a Ni/photoredox dual catalysis approach for the regioselective alkylarylation of dienes, offering a mild reaction that eliminates the need for stochiometric metal reductants. Broad substrate scope and mechanistic investigations are presented that support the proposed reaction mechanism.
