  1. 1. Photoredox catalysis harnessing oxygen-centered radicals

    Författare :Alica Ondrejkova; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oxygen-centered radical; photoredox catalysis; C-H functionalization; visible light;

    Sammanfattning : Visible light provides an abundant and renewable source of energy with an ample capacity to mediate chemical transformations. Photoredox catalysis utilizes this energy for the generation of high-energy radical intermediates and strategically employs these reactive species in versatile chemical transformations. LÄS MER

  3. 2. Green Chemistry in Chemical Education and Synthetic Applications of Sulfinamides

    Författare :Björn Blomkvist; Peter Dinér; José Alemán; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sulfinamide; Green Chemistry; Chiral Auxiliary; Photoredox; Teaching; Sulfinamid; Grön Kemi; Kiral Hjälpgrupp; Fotoredox; Undervisning; Kemi; Chemistry;

    Sammanfattning : The preparation of chiral molecules, i.e. compounds that are not identical to their mirror image, is of great interest in the field of organic chemistry. LÄS MER

  4. 3. Photoredox Catalysis Driven by Visible Light and Iron N-Heterocyclic Carbene Complexes

    Författare :Lisa de Groot; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoredox catalysis; iron N-heterocyclic carbene complexes; Fe-NHC; Visible light; ATRA; BHAS;

    Sammanfattning : Photoredox catalysis is a rapidly expanding field, in which organic transformations are catalysed using light. The most commonly used photoredox catalysts (PCs) are transition metal complexes which absorb in the visible region of the electromagnetic spectrum. LÄS MER

  5. 4. Structure-Property Relationships of Iron N-Heterocyclic Carbene Complexes : Synthesis, Characterization and Application

    Författare :Valtýr Freyr Hlynsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoredox catalysis; photovoltaics; photosensitizer; N-heterocyclic carbene NHC ; BHAS; synthesis; Organometallic chemistry; structure-property relationship; coordination chemistry; heteroleptic iron complexes; geometry; photophysics;

    Sammanfattning : Resulting from the general availability of first-row transition metals, compared to their second- and third-row counterparts, photosensitizers (PSs) based on metals like iron have gained interest as candidates to enable photochemistry from solar energy, a largely underutilized energy source. Iron complexes equivalent to other metal complexes, currently being used as PS, do lack some of the advantageous properties required to challenge the established PSs. LÄS MER

  7. 5. Photocatalysis beyond conventional precious metal complexes

    Författare :Rickard Lindroth; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heterogenization; Iron photocatalysis;

    Sammanfattning : Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. LÄS MER
