Sugita, Hajime published the artcileUnusual cyclic polymerization through Suzuki-Miyaura coupling of polyphenylene bearing diboronate at both ends with excess dibromophenylene, Recommanded Product: Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, the publication is Chemical Communications (Cambridge, United Kingdom) (2017), 53(2), 396-399, database is CAplus and MEDLINE.
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.
