Preparation of poly(fluorene)s using <i>trans</i>‐bis(dicyclohexylamine)palladium diacetate as a catalyst: Scope and limitations

Abstract

trans-Bis(dicyclohexylamine)palladium diacetate was tested in a Suzuki-type poly(fluorene) synthesis. Poly(9,9-dihexylfluorene) was prepared in only 2 h with alcohols as the solvent and KOH as the base. The concomitant occurrence of Suzuki coupling, debromination, hydrolytic deboronation, and hydroxy deboronation reactions was demonstrated and used in a such way that either dihydrogen-terminated or partly hydroxy-terminated poly(fluorene)s could be obtained.
