conventional directing template strategies via a covalent binding to the substrates are always hindered by prior stoichiometric installation and removal of the directing groups. Herein, we report a palladium-catalyzed meta-selective C–H olefination of aromatic carbonyl compounds by noncovalent hydrogen-bonding interaction. N,N′-Substituted ureas were engineered to serve as a H-bonding donor for binding
