Ruthenium(II)biscarboxylate complexes enabled the selectivealkylation of C−H and C−C bonds at the ortho‐ or meta‐position. ortho‐C−HAlkylations were achieved with 4‐, 5‐ as well as 6‐membered halocycloalkanes. Furthermore, the judicious choice of the directing group allowed for a full control of ortho‐/meta‐selectivities. Detailed mechanistic studies by experiment and computation were performed and
