Abstract

The Suzuki-Miyaura coupling polymerization of p-dibromophenylene and m-phenylenediboronic acid ester, as well as m-dibromophenylene and p-phenylenediboronic acid ester, and the combination of two meta-phenylene monomers in the presence of the t-Bu₃PPd(0) catalyst selectively afforded cyclic polyphenylenes with polyphenylene bearing boronate moieties at both ends when excess dibromophenylene was used.
