N‐tosylarylimines and alkynes via ruthenium(II)‐catalyzed CH bond activation and annulation is described. The catalytic reaction proceeds well with a broad substrate scope and in good yields. A possible mechanism is proposed that involves imine nitrogen chelation‐assisted ortho‐CH bond activation of the substrate, alkyne insertion, and intramolecular insertion of the CN Ts group into the CRu bond.
