1. New Materials in Environmental Catalysis
Sammanfattning : This thesis presents new approaches to the control of emissions within the field of environmental catalysis. Three catalytic systems; bimetallic catalysts, perovskites and promoted catalysts have been prepared and evaluated for complete oxidation of volatile organic compounds and for simultaneous conversion of CO, hydrocarbons and nitrogen oxides.

2. Synthesis of functionalized allylic, propargylic and allenylic compounds : Selective formation of C–B, C–C, C–CF3 and C-Si bonds
Sammanfattning : This thesis is focused on the development of new palladium and copper- mediated reactions for functionalization of alkenes and propargylic alcohol derivatives. The synthetic utility of the 1,2-diborylated butadienes synthesized in one of these processes has also been demonstrated. LÄS MER
3. Biomimetic Transition Metal Catalysts : Insights from Theoretical Modeling
Sammanfattning : The scientific interest in the chemistry of synthetic transition metal complexes is motivated by at least two arguments:1.These can be regarded as models of biological transition metal complexes, e.g. metalloenzymes, whose functions can be difficult to reveal in detail due to their complexity.

4. Direct conversion of methane-to-methanol in Cu-exchanged small-pore zeolites
Sammanfattning : Fossil fuel consumption continuous to increase worldwide and of all the fossil fuels, natural gas is growing the most. The combustion of natural gas, which mainly contains methane, is more environmentally friendly than oil or coal thanks to its high specific energy. LÄS MER
5. Transformations of Nitrosoarenes and Alkynyl Enones : Selective Synthesis of Nitrogen-Containing Compounds
Sammanfattning : The nitrogen atom plays a unique role in organic chemistry. It is abundantly found in organic materials and is responsible for the activity of many biologically relevant compounds. LÄS MER
