Ruthenium(II) pincer-catalyzed α-olefination of nitriles is reported. This simple protocol provides a transformation for the catalyticsynthesis of β-disubstituted vinyl nitriles using secondary alcohols. This catalytic method has an extensive substrate scope, as arylmethyl nitriles, heteroarylmethyl nitriles, and aliphatic nitriles as well as cyclic, acyclic, symmetrical, and unsymmetrical secondary
