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
控制位置选择性是过渡金属催化的 C-H 键功能化中最重要的方面之一。然而,通过与底物共价结合的常规导向模板策略总是受到先前化学计量安装和导向基团的去除的阻碍。在此,我们报告了通过非共价氢键相互作用对芳族羰基化合物进行间位选择性 C-H 烯化的钯催化。N,N'-取代的尿素被设计为用作与底物结合的氢键供体,同时通过集成的导向基团实现位点选择性控制。
