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

A composition includes an inorganic particle core and an initiator molecule chemically bonded thereto. The particle core is formed of a material having a dielectric constant of about fifteen or more. The initiator molecule includes a chain having about twenty or fewer carbon atoms and a phosphorous atom chemically bonded to an end of the chain. An alkyl derivative of an aryl moiety terminates another end of the chain.
