5-Cyanoimidazole was identified as an inexpensive ligand for nickel-catalyzed cross-electrophile couplings for the preparation of various alkylated arene products with good yields. Furthermore, the scope of reductive couplings could be expanded to challenging substrates, such as sterically hindered neopentyl halides.
