1. Mechanisms of Anion Reactions from the lab to ionospheres
Sammanfattning : A multitude of heavy neutral and ionic molecules have been discovered by the Cassini Plasma Spectrometer in the ionosphere of Saturn's largest moon Titan. However, only three cyano anions were explicitly identified there, namely CN-, C3N- and C5N-. LÄS MER
2. Nitriles in Prebiotic Chemistry and Astrobiology
Sammanfattning : Life appeared on Earth within a billion years of the planet’s formation. How? - no one knows. Theories regarding the origin of life involve reactions of molecules predicted to have existed on early Earth in what is called prebiotic chemistry. LÄS MER
3. Quantum Chemical Exploration of Nitriles in Prebiotic Chemistry and Astrobiology
Sammanfattning : The Universe hosts countless different chemical environments, such as planets, moons, comets and the interstellar medium. The diverse pressures, temperatures and chemical compositions of these environments make a wide variety of processes possible. LÄS MER
4. Dissociative recombination of organic molecular ions of relevance for interstellar clouds and Titan's upper atmosphere
Sammanfattning : This thesis presents experimental studies on the dissociative recombination (DR) of the organic molecular ions CD3CND+, CH2CHCNH+, CH3CH2CNH+, CD3CDO+, CH3CHO+ and DCOOD2+. The experiments were all performed at the heavy ion storage ring CRYRING at the Manne Siegbahn Laboratory in Stockholm, Sweden. LÄS MER
5. Palladium(II)-Catalysed Heck and Addition Reactions : Exploring Decarboxylative and Desulfitative Processes
Sammanfattning : Palladium complexes have the ability to catalyse cross-coupling of two organic moieties through the formation of transient metal-carbon bonds, thus bringing them closer to each other to facilitate the formation of a new bond. Palladium-catalysed coupling reactions are one of the most important carbon-carbon forming reactions available to organic chemists and many of these reactions rely on the reactivity of aryl-palladium complexes.
