method for the cross‐coupling of benzylic α‐trifluoromethylated alkylboron reagents with (hetero)aryl bromides is achieved through application of a photoredox/nickel dual catalytic system. The harsh conditions and high temperatures required by conventional Suzuki‐coupling protocols are avoided by exploitation of an odd‐electron pathway that permits roomtemperature transmetalation of these recalcitrant
