1. Hydroarylation of Fullerene C60 Using Arylboronic Acids via Rhodium Catalysis : Improving the Outcomes and Simplifying the Conditions
Abstract : Hydroarylation with arylboronic acids is one of the functionalization methods for synthesis of modified fullerenes. In this work, we provide a fast and reproducible one-phase method for hydroarylation of fullerene using boronic acids and an analytical HPLC method that efficiently separates unreacted C60 and product from a hydroarylation reaction mixture as well as a fulleropyrrolidine reaction mixture.

3. Asymmetric Synthesis and Mechanistic Insights of Transition-Metal-Catalyzed Hydrogenation
Abstract : The work presented in this thesis is focused on asymmetric synthesis and mechanistic insights of hydrogenations catalyzed by Ir-N,P- and Rh-diphosphine complexes. The developed methodologies provide an efficient catalytic system to access optically enriched compounds by exploiting the effect of the N,P ligand structure and investigating the enantioconvergent behavior.

4. Controlling the Reactivity and Selectivity in Iridium- and Rhodium-Catalyzed Asymmetric Hydrogenation
Abstract : The work presented in this thesis is mainly focused on the development of iridium- or rhodium-catalyzed asymmetric hydrogenation featuring a number of practical concepts including cascade reaction, kinetic resolution, desymmetrization, and dearomatization. The protocols rely on gaining control of the reactivity among different olefins or olefin precursor as well as maintaining chemo- and stereo-selectivity in the hydrogenation. READ MORE
