The terminal‐selective, remoteC(sp3)−H alkylation of alkenes was achieved by a relay process combining NiH‐catalyzed hydrometalation, chain walking, and alkylation. This method enables the construction of unfunctionalized C(sp3)−C(sp3) bonds under mild conditions from two simple feedstock chemicals, namely olefins and alkyl halides. The practical value of this transformation is further demonstrated

Reported here is a terminal‐selective, remote asymmetric hydroalkylation of olefins with racemic α‐bromo amides. The reaction proceeds by NiH‐catalyzed alkene isomerization and subsequent alkylation reaction, and can enantioconvergently introduce an unsymmetrical secondary alkyl group from a racemic α‐bromo amide onto a terminalC(sp3)−H position along the hydrocarbon chain of the alkene. This mild process
