The Mechanism of Ruthenium‐Catalyzed Directed C─H Arylation of Arenes: The Key Role of Bis‐Cyclometalated Intermediates

open access: yesAngewandte Chemie, EarlyView.
The mechanism of Ru‐catalyzed N‐directed C─H ortho‐arylation with haloarenes is addressed through experimental stoichiometric, catalytic kinetic, and DFT studies. These reveal a key role for bis‐cyclometallated ruthenium species and show bromoarene activation proceeds via a concerted oxidative addition.
