An efficient method for the direct allylation of alkylhalides catalyzed by simple cobalt(II) bromide has been developed. This reaction, using a variety of substituted allylicacetates or carbonates, provides the linear product as the major product. It displays broad substrate scope and good functional group tolerance.

A light-induced redox-neutral Ni-catalyzed sp3 C–H alkylation of unactivatedalkenes with alkyl bromides possessing β-hydrogens is described herein. The method is distinguished by its simplicity, wide scope, and exquisite regio- and chemoselectivity profile, thus offering an entry point to forge sp3–sp3 architectures.

An unprecedented reductive cross-coupling reaction of allylammonium salts with alkyl electrophiles has been established through C–N bond cleavage. A range of allylammonium bromides smoothly participated in the nickel-catalyzed zinc-mediated allyl–alkyl cross-electrophile coupling reaction with alkyliodides, delivering structurally diverse alkene products in moderate to good yields with high linear
