1. Dissociation dynamics of highly excited molecules: Theory and Experiment
Sammanfattning : This thesis presents studies on dissociation of two model molecules: Butadiene and Cyclopropane. Tunable synchrotron radiation was used to ionize or excite the molecules in the gas phase, and the momentum correlation of the resulting fragment ions were measured using a 3D momenta coincident ion spectroscopy.

2. Cyclopropane as refrigerant in small refrigeration systems
Sammanfattning : .... LÄS MER
3. Asymmetric Synthesis using Redox-Active Diazocompounds as Chiral Carbon Atom Precursors
Sammanfattning : This thesis summarizes the development of general and efficient methods to synthesize enantiomerically enriched cyclopropane compounds. The works reported herein exploit the opportunity presented by redox-active esters to explore the orthogonality between asymmetric carbene-transfer and geminal radical generation. LÄS MER
4. Quantum Chemical Cluster Modeling of Enzymatic Reactions
Sammanfattning : The Quantum chemical cluster approach has been shown to be quite powerful and efficient in the modeling of enzyme active sites and reaction mechanisms. In this thesis, the reaction mechanisms of several enzymes have been investigated using the hybrid density functional B3LYP. LÄS MER
5. Palladium-Catalyzed Synthesis and Transformation of Organoboranes
Sammanfattning : This thesis presents the development of new palladium-catalyzed transformations involving synthesis and application of allylborane reagents. In these reactions various palladium sources, including pincer complexes and commonly used catalysts were applied. LÄS MER
