Direct C-H functionalization of aryl ethers remains challenging owing to their low reactivity and selectivity. Herein, a novel strategy for nondirected C-H alkenylation of aryl ethers promoted by a dual ligand catalyst was demonstrated. This catalytic system readily achieved the highly efficient alkenylation of alkyl aryl ethers (anisole, phenetole, n-propyl phenyl ether, n-butyl phenyl ether and benzyl
芳基醚的直接CH官能化由于其低反应性和选择性而仍然具有挑战性。在本文中,证明了由双配体催化剂促进的芳基醚的非定向CH烯基化的新策略。该催化体系可轻松实现烷基芳基醚(苯甲醚,苯酚,正丙基苯基醚,正丁基苯基醚和苄基苯基醚),环状芳基醚(1,4-苯并二恶烷,2,3-二氢苯并呋喃)的高效烯基化,二苯并呋喃)和二苯氧化物。此外,所提出的方法已成功地用于含有芳基醚基序的复杂药物的后期修饰。有趣的是,本文开发的化合物显示出荧光性质,这将有助于其生物学应用。
