Manh V. Pham and Prof. Dr. Nicolai Cramer Aromatic Homologation by Non-Chelate-Assisted RhIII-Catalyzed CH Functionalization of Arenes with Alkynes Angewandte Chemie International Edition 53
Multi-ring circus: The aromatic homologation of unfunctionalized, directing-group-free arenes with internal alkynes is promoted by a rhodium(III) catalyst in conjugation with suitable oxidants. The method tolerates a variety of functional groups and delivers highly substituted and highly soluble condensed arenes. These products provide access to acene structures with important electronic and photophysical properties.
