Zwitterionic Nickel Catalyst for Carbonylative Polymerizations

Abstract Details

2011, Master of Science, University of Akron, Polymer Science.
The goal of this research project was to develop a catalyst for the copolymerization of carbon monoxide (CO) and epoxides and/or aldehydes. Zwitterionic palladium and nickel complexes were synthesized that contained bidentate phosphine-borate ligands. Under the assumption that a polymerization mechanism similar to the established cobalt-catalyzed copolymerization of CO and aziridines is applicable, the zwitterionic nature of the complexes were expected to posses the high activity of cationic metal-acyl bonds, while maintaining the anionic nature required for ion pairing during the polymerization. Characterization of the nickel complex was completed through NMR spectroscopy, FTIR spectroscopy, and X-ray crystallography. Upon completion of the metal complex syntheses a variety of polymerization conditions were screened, and the products were characterized by NMR and IR spectroscopy. Although the spectroscopic methods showed the system had activity, a pure polymer product was not obtained.
