Synthesis and reactivity of early transition metal "Frustrated Lewis Pairs"
… group recently introduced the new concept of "Frustrated Lewis Pairs" (FLP) wherein sterically demanding Lewis acids and bases do not interact in the expected donor-acceptor fashion, but rather exhibit unique reactivity. To date this concept of FLPs has been limited to main group systems. In …

Synthetic Studies in the Formation of Nitrogen Containing Compounds: From Simple Amines to Complex Natural Products
… we will discuss the progress toward the use of Frustrated Lewis pairs for the synthesis of chiral benzylic amines. Frustrated Lewis pairs have shown the ability to activate inert bonds such as H-H bonds mildly and selectively. Using these concepts as inspiration we attempted to activate C-H and …

Development of Main Group Systems for Small Molecules Activation
Frustrated Lewis pairs (FLP) have been introduced as an alternative to transition metal catalyst. Since the first discovery in 2006, FLP has found diverse applications in areas such as small molecules activation and catalysis. The present thesis has two major directions: 1) find new types of FLP; …

Sharing the Burden of Reactivity: Synthesis, Characterization, and Reactivity of Phosphino-Alkoxide First-Row Transition Metal Complexes
… complexes, bimetallic complexes, and frustrated Lewis pairs. Specifically, a phosphino-alkoxide ligand was developed to promote high-spin complex formation, produce unconventional geometries, and enable controlled dimerization. The complexes produced with this ligand were screened for …

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 …

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 …

Ionic liquids for main group catalysis
Lewis acidic ionic liquids, in particular chloroaluminate systems, have been found to be very effective catalysts for reactions such as Diels-Alder and Friedel-Crafts, and made their way to pilot and industrial processes, including oligomerisation of olefins (DifasolTM by IFP) and refinery …

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 …
