The nickelcatalyzed cross-coupling of alkyl and alkenyl Grignard reagents with arylnitrile derivatives affords good yields of the corresponding aryl alkanes or aryl alkenes via activation of the CCN bond. To prevent direct addition of the nucleophile to the nitrile group, the reactivity of the Grignard reagent was modulated by reaction with either LiOt-Bu or PhSLi prior to cross-coupling. The optimum
