Rapid access to structurally diversified polycyclic aromatic hydrocarbons (PAHs) in a controlled manner is of key significance in materials sciences. Herein, we describe a strategy featuring two distinct electrocatalytic C−H transformations for the synthesis of novel nonplanar PAHs. The combination of rhodaelectrooxidative C−H activation/[2+2+2] alkyne annulation of easily accessible boronic acids with
在材料科学中,以受控方式快速获得结构多样的多环芳烃(PAH)至关重要。在这里,我们描述了一种以两种不同的电催化CH转化为特征的策略,用于合成新型非平面PAH。易于获得的硼酸的rhodaelectrooxidative CH-H活化/ [2 + 2 + 2]炔烃环化与电催化环脱氢的组合,提供了模块化的途径,可替代地将PAHs与电作为可持续的氧化剂。全面分析了由此获得的多环芳烃的独特分子拓扑结构以及光物理和电子性质。这种金属电化学催化方法的独特功能通过合成有用的碘取代的PAH的化学选择性组装得到了证明。
