achieved under mild conditions with low catalyst loading. The diastereoselectivity of the reaction can be controlled by choosing the appropriate ancillary ligand (see scheme; coe=cyclooctene). The silylation products undergo further transformation such as oxidation or cross‐coupling.
C–C bond-forming reactions using Katritzky salts, their deaminative allylation remains a challenge. Inspired by the metallaphotoredox-catalyzed allylicsubstitution regime, here, we report the deaminative allylation of Katritzky salts via cobalt/organophotoredox dual catalysis. This cross-electrophile coupling enables regioselective allylation using a variety of allylic esters, overcoming the substrate

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
