Abstract
AbstractThe ruthenium‐catalyzed dehydrogenative borylation of 2‐arylpyridines with pinacolborane took place at ortho‐positions of the benzene ring. Density functional theory calculations and kinetic isotope effect experiments suggest that the catalytic cycle should involve oxidative addition of the CH bond, the rate‐determining σ‐bond metathesis of pinacolborane with the ruthenium hydride complex, and reductive elimination of the CB bond.
