preparation of nitrile‐containing building blocks is of interest due to their utility as synthetic intermediates and their prevalence in pharmaceuticals. As a result, significant efforts have been made to develop methods to access these motifs which rely on safer and non‐toxic sources of CN. Herein, we report that 2‐methyl‐2‐phenylpropanenitrile is an efficient, non‐toxic, electrophilic CN source for

generate and intercept nitrile anion equivalents using hydrogen transfercatalysis. Addition of α,β‐unsaturated nitriles to a pincer‐based Ru−H complex affords structurally characterized κ‐N‐coordinated keteniminates by selective 1,4‐hydride transfer. When generated in situ under catalytic hydrogenation conditions, electrophilic addition to the keteniminate was achieved using anhydrides to provide α‐cyanoacetates
