  1. 6. Synthesis and Structural Characterization of Copper(I) Complexes with Hard Donor Ligands

    Författare :Björn Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acetonitrile; ­ -Sparteine; Chloride; co-ordination chemistry; Phenoxide; Alkene; Bromide; crystal structure; Copper I ; Amine;

    Sammanfattning : Syntheses and crystal structures of nine new copper(I) complexes and one novel mixed-valence copper(I/II) complex are reported: two homoleptic phenoxides and eight complexes with N-donor ligands. The copper(I) and the copper(I/II) phenoxide complexes have been prepared by reactions between mesitylcopper(I) and 2-allyl-6-methylphenol in toluene. LÄS MER

  3. 7. Copper and Palladium-Mediated Transformationsof Allylic and Propargylic Substrates

    Författare :Tony S. N. Zhao; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is focused on the development of new palladium and copper-mediated reactions for functionalization of alkenes and propargylic alcohol derivatives. We have developed an efficient procedure for the synthesis of allenyl and propargyl boronate from propargylic carbonates and acetates. LÄS MER

  4. 8. The role of particles on initial atmospheric corrosion of copper and zinc : lateral distribution, secondary spreading and CO2-/SO2-influence

    Författare :Zhuo Yuan Chen; Christofer Leygraf; Jan-Erik Svensson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric corrosion; copper; zinc; NaCl particles; NH4 2SO4; Materials chemistry; Materialkemi;

    Sammanfattning : The role of sodium chloride (NaCl) particles and ammonium sulfate ((NH4)2SO4) particles on the initial atmospheric corrosion of copper and zinc was investigated under in situ and ex situ conditions using microgravimetry, FTIR spectroscopy, ion chromatography, scanning electron microscopy with x-ray microanalysis and the scanning Kelvin probe. For the first time, in situ infrared spectra were collected on a micron level during particle induced atmospheric corrosion using a recently developed experimental set-up for in situ FTIR microspectroscopy.
