1. Efficiency and Selectivity in the Chlorate Process
Abstract : This licentiate thesis presents experimental studies concerning two parts of the electrochemical cell in the chlorate process: a cathode and an anode.Newly synthesized MnOx electrodes were investigated for the cathodic reaction, hydrogen evolution reaction (HER) in the chlorate process.

2. Iron catalyzed C-C coupling reactions - mechanistic investigations
Abstract : The mechanism of the iron catalyzed cross coupling of aryl electrophiles with alkyl Grignard reagents was studied. The reaction proceeds via a rate-limiting oxidative addition of the aryl halide to an Fe(I) complex generated in situ. A transmetalation from an aryl Grignard reagent occurs either before or after the oxidative addition. READ MORE

3. Studies on Palladium-Catalyzed Carbocyclizations of Allene-Substituted Olefins and 1,3-Dienes
Abstract : This thesis describes the development and mechanistic studies of carbocyclization reactions of allene-substituted olefins and 1,3-dienes, catalyzed by palladium(0) and palladium(II). These reactions results in the formation of [n,3,0] bicyclic systems (n = 3-5) with high stereoselectivity and in good to excellent yields. READ MORE

4. Development of Palladium-Catalyzed Transformations Involving η1-Allypalladium Species
Abstract : 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. READ MORE

5. Immobilisation of Ru-Based Molecular Catalysts for Electrochemical Water Oxidation
Abstract : Artificial photosynthesis requires catalysts for efficient and selective conversions of small molecules. Molecular catalysts are advantageous to use in these instances as they offer precise control over chemical reactivity. READ MORE
