  3. 2. Palladium(II)-Catalysed Heck and Addition Reactions : Exploring Decarboxylative and Desulfitative Processes

    Författare :Bobo Skillinghaug; Mats Larhed; Antonio de la Hoz Ayuso; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium; catalysis; palladium II catalysis; synthesis; Heck; carboxylic acid; sulfinic acid; sodium sulfinate; nitrile; styrene; ketone; aryl ketone; electrospray ionization mass spectrometry; density functional theory; microwave heating; continuous flow; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    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.

  4. 3. Metal-Free O- and C-Arylation with Diaryliodonium Salts

    Författare :Erik Lindstedt; Berit Olofsson; Kilian Muñiz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hypervalent Iodine; Alkyl Aryl Ethers; Nitro Compounds; Alcohols; Diaryliodonium Salts; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis concerns the development of metal-free applications using diaryliodonium salts. The first project describes an arylation protocol of allylic and benzylic alcohols in aqueous media. The method proceeds under mild conditions and the ether products were obtained in moderate to good yields. LÄS MER

  5. 4. Engineered Alcohol Dehydrogenases for Stereoselective Chemical Transformations

    Författare :Thilak Reddy Enugala; Mikael Widersten; Manfred T. Reetz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alcohol dehydrogenase-A; biocatalysts; protein engineering; enzyme kinetics; sec-alcohols; ketones; stereoselectivity; regioselectivity; substrate selectivity and promiscuity.; Biokemi; Biochemistry;

    Sammanfattning : Enzymes are biomolecules built from amino acids and catalyze the chemical transformations in a cell. Enzymes are by nature stereoselective, biodegradable, environmentally friendly, and can perform catalysis in aqueous solutions and at ambient temperatures. LÄS MER
