Isomerization under Nickel and Photoredox Catalysis
Cross‐coupling reactions of alkenyl halides with 4‐alkyl‐1,4‐dihydropyridines as alkylation reagents have been achieved by combination of nickel and photoredox catalysts. Alkenyl halides bearing alkyl and aryl substituents are available. Particularly, in the use of aryl‐substituted alkenyl halides, cross‐coupling reactions are associated with E to Z isomerization of alkenes. Thus, Z‐isomers of the
