The efficient 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 the synthesis of nitrile‐bearing quaternary centers by a thermodynamic transnitrilation and anion‐relay strategy. This one‐pot process leads to nitrile products resulting from the gem ‐difunctionalization of alkyl lithium reagents.
