Abstract
AbstractA palladium‐catalyzed two‐fold annulation reaction of 2,6‐dihalogenobiphenyls with o‐chloroaromatic carboxylic acids has been developed. This method enables the synthesis of various dibenzo[fg,op]tetracenes and azadibenzo[fg,op]tetracenes. Preliminary investigations indicate that the resulting product, dimethyl 5,6,12,13‐tetrakis(hexyloxy)dibenzo[fg,op]tetracene‐2,9‐dicarboxylate, demonstrates favorable liquid‐crystalline properties.
