A Ni-catalyzed process for the cross-coupling of tertiary alkyl nucleophiles and aryl bromides is extremely general for a wide range of electrophiles and generally occurs with little isomerization. The same procedure also accommodates the use of aryl triflates, vinyl chlorides, and vinyl bromides as the electrophilic component.
