Thesis (Ph.D.)--New York University, 2015.

Supported catalysis is an attractive approach for sustainable chemistry. Among the various support systems, core-shell micelles can impact a catalytic reaction beyond sole recycling of catalysts. This core-shell micelle support provides a stable platform for catalyst ligation, along with isolated domains to conduct two or more incompatible catalytic reactions in a one-pot tandem fashion. This thesis aims to develop a tandem catalytic reaction involving two incompatible transition metal-catalyzed transformations. Such a system should proceed in one-pot by utilizing the site-isolation and multi-phase properties of core-shell micelle supports.

520 $a Supported catalysis is an attractive approach for sustainable chemistry. Among the various support systems, core-shell micelles can impact a catalytic reaction beyond sole recycling of catalysts. This core-shell micelle support provides a stable platform for catalyst ligation, along with isolated domains to conduct two or more incompatible catalytic reactions in a one-pot tandem fashion. This thesis aims to develop a tandem catalytic reaction involving two incompatible transition metal-catalyzed transformations. Such a system should proceed in one-pot by utilizing the site-isolation and multi-phase properties of core-shell micelle supports.
520 $a Chapters 2 and 3 present research focused on micelle-supported Co-salen catalyzed hydrolytic kinetic resolution (HKR) of epoxides and micelle supported Ru-porphyrin-catalyzed epoxidation of terminal olefins, respectively. The goal of these two chapters is to develop an epoxidation-HKR tandem reaction based on these two catalysts. Chapter 2 introduces a unique substrate selectivity based upon the hydrophobicity of the substrate. Chapter 3 demonstrates a mild epoxidation procedure using hydrogen peroxide as the oxidant, a process that proceeds at room temperature and in pure aqueous media. The tandem reaction, however, could not be realized for these two transformations since the hydrogen peroxide used in the epoxidation step over-oxidizes the HKR products.
520 $a Chapter 4 presents the first one-pot tandem reactions using two transition metal catalysts. A micelle supported multifunctional catalytic system was developed involving Co-catalyzed alkyne hydration and Rh-catalyzed asymmetric transfer hydrogenation (ATH). In particular, a shell cross-linked micelle was synthesized containing Co-porphyrin in the micelle core and Rh-TsDPEN in the micelle shell. Taking advantage of the compartmentalization in the micelle support, the normally incompatible alkyne hydration and ATH reactions proceed in one-pot in a tandem catalysis process.
520 $a Chapter 5 presents a shell cross-linked micelle with a basic core and an acidic shell designed for acid-base tandem reactions. The compartmentalization allows for wolf and lamb-type reactions. Chapter 6 presents preliminary results towards a micelle supported Rh-catalyzed ATH and DMAP-catalyzed acylation in a one-pot manner. Finally, Chapter 7 summarizes the conclusions of the thesis and presents potential extensions of the research developed in this thesis.
