Abstract

A repetitive two-step method involving the Pd-catalyzed Suzuki-Miyaura coupling of hydroxyterphenylboronic acid and the subsequent nonaflation of the hydroxy group has been developed for the synthesis of oligophenylenes. This method readily afforded o,o,p- and o,p-oligophenylenes with defined chain lengths. X-ray crystallography was employed to obtain the structure of the o,p-oligophenylene 9-mer.
Keywords: palladium; Suzuki-Miyaura coupling; oligoarene; nonaflate palladium; Suzuki-Miyaura coupling; oligoarene; nonaflate
