  1. 1. Asymmetric Synthesis and Mechanistic Studies on Copper(I)-Catalyzed Substitution of Allylic Substrates

    Författare :Jakob Norinder; Jan-Erling Bäckvall; Norbert Krause; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; copper; allylic substitution; ferrocene; DYKAT; cross-coupling; homo-coupling; DFT; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis deals with the copper-catalyzed substitution of allylic substrates.In the first part of this thesis, the synthesis of a series of metallocenethiolates is described. The thiolates were examined as ligands in the enantioselective copper(I)-catalyzed γ-substitution of allylic acetates. LÄS MER

  3. 2. New Cu-I cluster compounds with luminescent properties

    Författare :Ehsan Jalilian; Sven Lidin; Torbjörn Gustafsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Copper I iodide; structure determination; luminescence; TDDFT; Materials chemistry; Materialkemi; Materials Chemistry; materialkemi;

    Sammanfattning : The aim of this thesis has been to investigate how the synthesis route, choice of solvent and counter-ions effects the crystallization of Cu(I)I systems, and to investigate the correlation between the structure and luminescence properties of the systems. In order to do so a series of compounds based on an anion containing Cu(I)I, stabilized by organic cations have been produced. LÄS MER

  4. 3. New Applications of Monoorganocopper/Iodotrimethylsilane Reagents in Conjugate Additions

    Författare :Magnus Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beta-unsaturated; halosilane; conjugate addition; alpha; copper iodide; copper acetylides; organocopper; iodotrimethylsilane; Claisen rearrangement;

    Sammanfattning : The thesis reports new applications of monoorganocopper compounds, RCu(LiI), and iodotrimethylsilane in conjugate additions. The present investigation demonstrates conjugate addition of alkylcopper compounds and iodotrimethylsilane to reactive .alpha.,. LÄS MER

  5. 4. Diffusion of Radionuclides in Bentonite Clay : Laboratory and in sity Studies

    Författare :Mats Jansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; cation; anion; diffusion; sorption; cobalt; caesium; strontium; iodide; pertechnetate; surface diffusion; in situ; Chemistry; Kemi;

    Sammanfattning : This thesis deals with the diffusion of ions in compactedbentonite clay. Laboratory experiments were performed toexamine in detail different processes that affect thediffusion. To demonstrate that the results obtained from thelaboratory investigations are valid under in situ conditions,two different kinds of in situ experiments were performed. LÄS MER
