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. Selective monofunctionalization of CO bonds in the presence of ortho CH bonds was also achieved.
