Arylnitriles have been found to participate in cross-coupling and amination reactions via nickel-catalyzed activation of the C-CNbond. With the development of these synthetically useful transformations, arylnitriles can now be considered along with aryl halides and sulfonates as viable substrates for these types of reactions.
