to polycyclic arenes. Herein, we disclose a nondirected annulation approach of unactivated simple arenes. The palladium-catalyzed 2-fold C-H arylation event facilitates tandem C-C linkage relays to furnish fully benzenoid triphenylene frameworks using cyclic diaryliodonium salts. The inseparable regioisomeric mixture of 1- and 2-methyltriphenylenes is identified by the combined analysis of ion mobility-mass
环状π延伸化学为多环芳烃的合成提供了一条简洁的途径。在此,我们公开了未激活的简单芳烃的非定向环行方法。钯催化的2倍CH芳基化反应可促进串联CC连接继电器使用环状二芳基碘鎓盐提供完全的苯并三苯并菲骨架。通过离子迁移质谱,气相红外光谱和分子模拟研究的组合分析,可以确定1-和2-甲基三亚苯基不可分离的区域异构体混合物。
