ligand-controlled nickel migration/arylation. This general protocol allows the use of abundant and bench-stable alkyl bromides and aryl bromides for the synthesis of a wide range of structurally diverse 1,1-diarylalkanes in excellent yields and high regioselectivities under mild conditions. We also demonstrated that alkyl bromide could be replaced by the proposed olefin intermediate while using n-propyl bromide/Mn0

cross-coupling has been achieved through NiH-catalyzed chainwalking and subsequent cross-coupling from two abundant starting materials, alkyl bromides, and carboxylicacids. This strategy allows the direct acylation of the benzylic sp3 C–H bond with high yield as a single regioisomer. As an alternative, the alkyl bromide could be replaced by the proposed olefin intermediate and commercially available n-PrBr
