for remote C7–H functionalizations of the naphthalene rings is greatly challenging. Disclosed herein is an example of direct and regioselective arylation of the naphthalene rings at the C7 position that is promoted by F+ reagents. This protocol features good tolerance of reactive functional groups, mild reaction conditions, and simple reaction system. By control experiments, a kinetic isotope effect (KIE)
萘环的远程C7–H官能化策略的开发非常具有挑战性。本文公开了由F +试剂促进的在C7位的
萘环的直接和区域选择性芳基化的例子。该方案具有对反应性官能团的良好耐受性,温和的反应条件和简单的反应体系。通过对照实验,动力学同位素效应(KIE)实验和NMR实验,已经清楚地说明了涉及碳
钯/芳基迁移的机理途径。除简单的导向功能外,空间受阻的N-(叔丁基)酰胺在通过碳
钯/芳基迁移的区域选择性控制中也发挥着重要作用。
