Bimetallic Palladium Catalysis: Direct Observation of Pd(III)–Pd(III) Intermediates
(American Chemical Society, 2009)\(PhI(OAc)_2\) is a common oxidant for Pd-catalyzed C−H bond functionalizations. Mechanistic hypotheses since the 1960s have suggested a Pd(II)/Pd(IV) mechanism. Here we present evidence for the relevance of bimetallic ... -
A Biocompatible Alkene Hydrogenation Merges Organic Synthesis with Microbial Metabolism
(Wiley-Blackwell, 2014)Organic chemists and metabolic engineers use largely orthogonal technologies to construct essential small molecules like pharmaceuticals and commodity chemicals. While chemists have leveraged the unique capabilities of ... -
Chiral Dual-Hydrogen-Bond Donors Catalyze Highly Enantioselective Cyclization Reactions
(2022-01-18)In Chapter 1, we describe the development and mechanistic analysis of highly enantioselective bioinspired cyclization reactions of monoterpene derivatives catalyzed by chiral ureas. From a detailed series of mechanistic ... -
Iron-Catalyzed 1,4-Hydroboration of 1,3-Dienes
(American Chemical Society, 2009)A chemo-, regio-, and stereoselective iron-catalyzed 1,4-hydroboration of dienes that affords γ-disubstituted allylboranes has been developed. 1,4-Hydroboration of 2-substituted dienes forms allylborane products with ... -
Metal-Ligand Multiple Bonds in High-Spin Complexes
(2012-07-23)The chemistry of late first row transition metals supported by dipyrromethane and dipyrromethene ligands bearing sterically bulky substituents was explored. Transition metal complexes (Mn, Fe, Co, Ni, Zn) of the dipyrromethane ... -
Reactions of Diketones and N-Allenoyloxazolidinones Catalyzed by Metal-Bis(oxazoline) Complexes
(2013-02-25)This dissertation describes the investigation of the utility of metal–bis(oxazoline) complexes in catalytic asymmetric reactions. The development of Cu(II)-catalyzed regio- and enantioselective additions of silylketenthioacetals ... -
Selective reactions of tertiary carbocations
(2020-12-07)Carbocations are fundamental intermediates in organic chemistry. Due to their high reactivity, they participate in a range of reactions enabling the synthesis of a variety of products from a single starting-material. A ... -
Single-Crystal Palladium-Silver Alloy Model Systems for Heterogeneous Catalysis
(2022-01-06)There is considerable interest among those in academia and in the industry in the use of metal alloys to combine the effect of the high reactivity of one component metal with the selectivity derived from a second, less ...
