Site-Selective 4+2 and 4+3 Annulations of Arylboronic Acids with Cyclic Diaryliodoniums for Polycyclic Arenes Synthesis

Key Points

• Investigate the synthesis of functionalized triphenylenes using arylboronic acids and cyclic diaryliodonium salts.
• Utilized tandem Suzuki-Miyaura and intramolecular C-C coupling techniques.
• Employed arylboronic acids in the presence of cyclic diaryliodonium salts.
• Examined scalability for large-sized polycyclic arenas.
• Successfully synthesized functionalized triphenylenes.
• Demonstrated site-selective [4+2] and [4+3] annulations.
• Expanded the scope of polycyclic aromatic compound synthesis.
