- Living Radical Polymerization with Active Catalysts—Promotion of Catalytic Cycle via Dynamic Transformation of the Metal Complex
Abstract
This comprehensive article summarizes our recent efforts to enhance the catalytic activity for living radical polymerization. We designed ligands, solvents and cocatalysts to promote dynamic transformation of the metal complex that is responsible for the catalysis, i.e., the reversible activation of carbon-halogen bond via a one-electron redox reaction. The catalytic activity of ruthenium complexes was dramatically enhanced, which allowed a universal catalysis for a variety of functional monomers, a highly active catalysis in water, and an autonomous catalysis independent of cocatalyst. More importantly, the activity was high enough to reduce the catalyst amount without any loss of controllability, even for the syntheses of higher molecular weight polymers and block copolymers. Iron- and nickel-based complexes were also developed to provide improved catalysis, i.e., faster polymerization and narrower molecular weight distribution than the vanguards. Importantly, some of them were tolerant of polar groups to control the polymerization of functional monomers.<br>
