Importance of the Balance of Interaction between Palladium Catalyst and Aromatic pi-Face for Unstoichiometric Suzuki-Miyaura Coupling Polymerization: Effective Pd cataCXium A Catalyst for Fluorene and Cyclopentadithiophene Monomers
Palladium cataCXium A catalyst was more effective than t-Bu3PPd catalyst for unstoichiometric Suzuki-Miyaura coupling polymerization of excess dibromofluorene with pinacol fluorenediboronate or pinacol benzothiadiazoleboronate, affording high-molecular-weight conjugated polymers with pinacol boronate ends. Furthermore, polymerization of excess dibromocyclopentadithiophene and pinacol benzothiadiazolediboronate with this Pd catalyst yielded high-molecular-weight donoracceptor conjugated alternating copolymer with boronate ends.
