iridium‐catalyzed intermolecular dehydrogenative silylation of C(sp2)H bonds of polycyclic aromatic compounds without directing groups. The reaction produced various arylsilanes through both SiH and CH bond activation, with hydrogen as the sole byproduct. Reactivity was affected by the electronic nature of the aromatic compounds, and silylation of electron‐deficient and polycyclic aromatic compounds proceeded
这项研究描述了铱催化的无环基团的多环芳族化合物的C(sp 2)H键的分子间脱氢甲硅烷基化反应。该反应通过两个硅产生的各种芳基硅烷 H和13 C H键活化,用氢作为唯一的副产物。反应性受芳香族化合物电子性质的影响,缺电子和多环芳香族化合物的甲硅烷基化反应有效进行。位点选择性主要受空间因素控制。因此,与芳香族化合物的一般亲电官能化所观察到的相比,当前的官能化以相反的化学选择性和位点选择性进行。
