A series of octa-R-substituted bromo-s-hydrindacenes, “Rind-Br,” have been synthesized by a sequence of the Lewis acid catalyzed intramolecular Friedel–Crafts reaction, bromination and vice versa. Their structural features and physical properties depend on the eight R-substituents at the four benzylic positions on the s-hydrindacenyl skeleton. The molecular structures of the Rind-Br have been confirmed by X-ray crystallography, indicating the unique structural diversities of the bulky Rind groups.
