21. Development of Palladium-Catalyzed Transformations Involving η1-Allypalladium Species
Sammanfattning : This thesis is focused on investigation of the structure, reactivity and isomerization reactions of η1-allylpalladium complexes, which are key intermediates in catalytic transformations. The first part of this thesis concerns the structure and reactivity of bis-allylpalladium complexes. LÄS MER
22. [11C]Carbon Monoxide in Rhodium-/Palladium-Mediated Carbonylation Reactions
Sammanfattning : Methods for the 11C-labeling of carbonyl compounds applicable in the preparation of radiotracers for Positron Emission Tomography (PET) are described. To this end [11C]carbon monoxide at low concentration was used in transition metal- mediated reactions. LÄS MER
23. Palladium catalysis in the synthesis of covalently linked diporphyrins
Sammanfattning : .... LÄS MER
24. Palladium(II)-Catalyzed Coupling Reactions
Sammanfattning : Sustainable chemical processes are becoming increasingly important in all fields of synthetic chemistry. Catalysis can play an important role in developing environmentally benign chemical processes, and transition metals have an important role to play in the area of green chemistry. LÄS MER
25. Palladium(II)-Catalyzed Oxidative Carbocyclization : Stereoselective Formation of C–C and C–B Bonds
Sammanfattning : Transition metal catalysis has emerged as one of the most versatile methods for the selective formation of carbon–carbon and carbon–heteroatom bonds. In particular, oxidative carbon–carbon bond forming reactions have been widely studied due to their atom economic feature. LÄS MER
