  5. 9. Palladium(II)-catalyzed 1,4-oxidations of 1,3-dienes : Development of an asymmetric version and synthetic applications

    Författare :Andreas Palmgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : In this thesis the development of an asymmetric version and synthetic applications of the Pd(II)-catalyzed 1,4-oxidation of conjugated dienes are described. The thesis is divided into four parts:(i) The first part concerns the design and synthesis of chiral p-benzoquinones as ligands in the Pd(II)-catalyzed 1,4-diacetoxylation. LÄS MER

  7. 10. Oxidation and reduction reactions of the water-oxidizing complex in photosystem II

    Författare :Long Vo Pham; Johannes Messinger; Imre Vass; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosystem II PSII ; oxidation; reduction; flash induced oxygen evolution pattern FIOP ; water; oxygen; global fitting program GFP ; thylakoids; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : The oxygen that we breathe and food that we eat are products of the natural photosynthesis. Molecular oxygen is crucial for life on Earth owing to its role in the glycolysis and citric acid pathways that yield in aerobic organisms the energy-rich ATP molecules. LÄS MER
