1. 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.

2. 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
3. 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.

4. Sustainable methods for the preparation of diverse Au(I) complexes
Sammanfattning : Over the last three decades, the role of Au(I) complexes has become increasingly important within medicinal chemistry, material applications and synthesis. Alas, their preparation remains reliant on harsh reaction conditions, hazardous solvents, exogenous additives and, often, high reaction temperatures. LÄS MER
5. 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
