Abstract:

Olefin polymerization catalysts containing redox-active moieties that may be tuned in situ via electrochemical or chemical oxidation and reduction were synthesized and examined. The redox capable functionalities were incorporated into specifically chosen ligand frameworks and metallated using organometallic reagents so as to produce precatalysts that could be activated using methylaluminoxane, borane, or boronate-based activators. Those catalysts were shown to be active toward olefin polymerizations,their electrochemistry studied, and their in situ switchability is currently underway yielding many promising results.
