Rare-Earth and Actinide Organometallic Chemistry: A Computational Approach

Abstract:

Electronic structure calculations of rare-earth and actinide organometallic complexes are intrinsically challenging due to competition between metal oxidation states, near-degeneracies among 6s-, 5d-, and 4f-orbitals, and relativistic effects. In this talk, I will demonstrate that density functional approximations (DFAs), particularly (hybrid) meta-GGA functionals such as TPSS and TPSSh, can serve as effective and reliable tools for understanding and advancing rare-earth and actinide chemistry.

Synthesis, Characterization, and Reactivity Studies on Transition Metal Amidophenolate Complexes

Abstract:

Catecholate-type ligands on transition metals have demonstrated the ability to act as proton and electron reservoirs, enabling diverse chemical transformations. This dissertation investigates how redox-active amidophenolate ligands control the electronic structure, reactivity and physical properties of transition metal complexes.

From multifunctional linkers to catalysis: study of multiomics, hydroselenation, N–H insertion, and morpholine bioisosteres

Abstract: 

My Ph.D. research has encompassed areas in synthetic organic chemistry and chemical biology including the development of multifunctional linkers for an application in expansion microscopy, anti-Markovnikov hydroselenation of olefins, enantioselective pyrazole alkylation via N–H insertion, and intramolecular hydroamination to access scaffolds with bioisostere potential. Collectively, these studies have enabled the design of functional molecules and the development of novel transformations.

Chiral Lewis Acid Catalysis for P-Stereogenic Compounds: From Ligands to Therapeutics and Beyond

Abstract: 

Compounds containing stereogenic phosphorus atoms played a historically important role in the development of asymmetric catalysis, exemplified by early P-chiral phosphine ligands such as DIPAMP. More recently, P-stereogenic motifs have emerged in medicinal chemistry, as a growing number of drugs contain stereogenic P(V) centers bearing predominantly phosphorus–heteroatom bonds, which present distinct synthetic challenges.
