  2. 1. N-Heterocyclic Carbene Catalysis in Organic Synthesis - A Green Chemistry Approach

    Author : Linda Ta; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aerobic oxidation; ionic liquid; sustainability; NHC catalysis; oxidative NHC catalysis; green chemistry; OTHO; Organocatalysis;

    Abstract : The twelve principles of green chemistry were created as a response to the multiple environmental issues caused by the release of waste from the chemical industry. The principles acts as a guide in the development of sustainable chemical processes for the syntheses of important molecules needed to sustain our living standards. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Aerobic Oxidative N-Heterocyclic Carbene Catalysis via Multistep Electron Transfer - Method Development and Applications

    Author : Anton Axelsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene; asymmetric synthesis; esterification; glycerol; electron transfer mediator; green chemistry; telescoped reaction; Organocatalysis; aerobic oxidation; dihydropyranone;

    Abstract : Oxidation reactions are ubiquitous in synthetic chemistry, but generally suffer from formation of large amounts of potentially toxic byproducts. Aerial oxygen represents an ideal oxidant since it is inexpensive, non-toxic and only forms water as a byproduct. READ MORE
