Ruthenium‐catalyzed selective monoalkenylation of ortho CO or CN bonds of aromatic ketones was achieved. The reaction allowed the direct comparison of the relative reactivities of the cleavage of different carbon‐heteroatom bonds, thus suggesting an unconventional chemoselectivity, where smaller, more‐electron‐donating groups are more easily cleaved.
