1. Diaryliodonium Salts : Synthesis, Applications and Computational Investigations
Sammanfattning : Organic chemists have the ability to create complex organic molecules by connecting molecular building blocks in different ways. To name a few, these molecules are used as medicines, pesticides or in our household electronics, and are therefore crucial to life as we know it. LÄS MER
2. New Arylation Strategies Based on Organomain Group Reactivity
Sammanfattning : The work in this thesis describes the development of new heteroarylation methodology based on transition metal-catalysed C-H functionalisation and the properties of organomain group compounds. The underlying reaction mechanisms and reactivity patterns of the (hetero)arene substrates are also investigated. LÄS MER
3. Control of Aryne Capture Regioselectivity via Fluoroboronate-induced Distortion
Sammanfattning : Arynes are valued as extremely versatile electrophilic intermediates. Control over the regioselectivity with which arynes react is typically achieved using comparatively simple and/or chemically inutile substituents close to the reactive triple bond. LÄS MER
4. Ruthenium-catalyzed C-H Functionalization of (Hetero)arenes
Sammanfattning : This thesis concerned about the Ru-catalyzed C-H functionalizations on the synthesis of 2-arylindole unit, silylation of heteroarenes and preparation of aryne precursor.In the first project, we developed the Ru-catalyzed C2-H arylation of N-(2-pyrimidyl) indoles and pyrroles with nucleophilic arylboronic acids under oxidative conditions.

5. New Strategies for Transition Metal-mediated (Hetero)arene Functionalization
Sammanfattning : This thesis describes new approaches to achieve efficient and selective (hetero)arene derivatization using transition metals. The main focus falls on the use of strategies based on C–H activation and organo-main group reactivity to render the synthesis of various (hetero)arene derivatives more direct, efficient, regioselective and sustainable.
