Nickel-Catalyzed Cross-Coupling of Aryl Bromides with Tertiary Grignard Reagents Utilizing Donor-Functionalized N-Heterocyclic Carbenes (NHCs)

One, two or three? The utilization of sterically hindered alkyl substrates represents a major challenge of the present cross‐coupling methodology. The nickel‐catalyzed Kumada cross‐ coupling of tertiary alkyl Grignard reagents with aryl bromides allows this difficult reaction with numerous different...
