Frustrated Lewis Pair Reactivity of Phosphino-Phosphenium Cations
The field of “frustrated Lewis pairs” (FLPs) broke the century-old paradigm that activation and cleavage of small molecules such as H2 belonged to the realm of transition metal chemistry. Since Stephan and co-workers’ seminal report on reversible H2 activation using a main-group phosphinoborane, the …

Developing hydrogen oxidation electrocatalysts using a frustrated Lewis pair approach
… of such metals limits their economic viability. Frustrated Lewis pairs (FLPs) are capable of heterolytically cleaving hydrogen, and have found application in hydrogenation chemistry. In this thesis, the hydrogen-activating ability of FLPs is exploited for the development of new, metal-free …

DFT Studies of the Organocatalytic Aldol Reaction and a Frustrated Lewis Pair
… reaction and the chiral backbone Frustrated Lewis Pair (FLP) system served as a valuable tool for experimental purposes. This thesis describes methods to consider different transition states of the proline- catalyzed α-chlorination aldol reaction to determine the reasonable …

FRUSTRATED LEWIS PAIR-MEDIATED SELECTIVE C–F BOND ACTIVATION AND SUBSEQUENT POST-FUNCTIONALIZATION OF POLYFLUOROALKANES
… functionalized. We have developed a Frustrated Lewis Pair (FLP) mediated C-F bond activation which allows selective monodefluorination of polyfluoroalkanes via base capture of intermediate fluorocarbocations. This methodology can be applied to aromatic, heteroaromatic and non-aromatic …

Harnessing Aluminum Radicals via Heterobimetallic Complexes for Small-molecule Activation
… as water and ammonia, switchable two-electron frustrated Lewis pair reactivity, photochemically induced radical pathways, and cooperative CO₂ activation through stepwise single-electron mechanisms. These concepts are further extended to multistate redox platforms and ligand-centered diradical …

A Lewis Acidic Stroll Through the p-Block
Since the inception of frustrated Lewis pair (FLP) chemistry more than a decade ago, the development of an assortment of main group Lewis acids in the literature has contributed to the enrichment and diversification of FLP reactivity to achieve transition metal-like chemistry. While most of the …

Synthesis and reactivity of ortho-carborane functionalized boron species.
… and bulky ortho-carborane substituents as Lewis acids for Frustrated Lewis Pair (FLP) chemistry. FLP chemistry is a three-component reaction that involves the use of a Lewis acid (LA), Lewis base (LB) and a substrate. This chemistry has been applied in bond activation reactions including …

Design of Lewis Acidic Pnictenium Ions Using Carbone and Capping Arene Ligands for Bond Functionalization
… due to isolation of low coordinate, subvalent or Lewis acidic compounds that can mediate reactivity traditionally reserved for their d block counterparts. Ligand strategies play a key role in the isolation of such species. Anionic ligands with large steric profiles, as well as carbenes, have been …
