Development Of Highly Efficient Catalyst And Reactions For Organic Synthesis: Monophosphine-Coordinated Palladacycle Complexes For Cross-Coupling Reactions/Polymerizations, Jie Dong
Dissertations, Theses, and Capstone Projects
Transition metal-catalyzed cross-coupling reactions such as Suzuki-Miyaura cross-couplings, are among the most powerful transformations in organic synthesis. They have been extensively used for the synthesis of a wide variety of organic compounds. Recently the Suzuki cross-coupling reaction has been extended to conjugated polymer synthesis, especially the controlled Suzuki cross-coupling polymerization for polymers with the desired length. My research is on developing highly efficient monophosphine-coordinated palladacycle complexes for cross-coupling reactions/polymerizations.
Based on the understanding of transition metal-catalyzed Suzuki cross-coupling reactions including polymerization, my dissertation started with Pd(0)- and Ni(0)-catalyzed borylation reactions of aryl halides and tosylates with bis(pinacolato)diboron to access arylboronates …

Development Of Palladium(0)-Catalyzed Suzuki Cross-Coupling Polymerizations, Wei Peng
Dissertations, Theses, and Capstone Projects
The synthesis of well-defined and high molecular weight π-conjugated polymers under mild condition within short reaction time is a challenging and important task in both organic chemistry and polymer chemistry. As one of the most efficient and high tolerance to solvents and reaction conditions, palladium(0)-catalyzed cross-coupling reactions would give us a good chance to achieve the goal. Thus, my Ph. D dissertation research projects focused on developing Pd(0)-catalyzed Suzuki cross-coupling polymerization reactions including controlled ones.
My research first studied t-Bu3P-coordinated 2-phenylaniline-based palladacycle complex catalyzed Suzuki cross-coupling polymerization of aryl dibromides with aryldiboronic acids at room temperature. Based …
