  1. 1. New C-C coupling Reactions Enabled by Main-group Organometallics

    Författare :Kilian Colas; Abraham Mendoza; David Procter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C-C coupling; organometallics; aluminum; magnesium; Grignard; turbo-Hauser-bases; piperazines; sulfur; ketones; organisk kemi; Organic Chemistry;

    Sammanfattning : The carbon-carbon bond has always been at the very core of chemical research. Strategies for the creation of C−C bonds are one of the keys to the construction game that organic chemists play with the building blocks provided by Nature, with the ultimate goal of producing useful molecular structures that will serve society as medicines, materials, imaging tools, catalysts, and ligands (to mention but a few).

  3. 2. Regenerable Organochalcogen Antioxidants : An Explorative Study

    Författare :Jiajie Yan; Lars Engman; David J. Procter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; autoxidation; antioxidant; selenium; tellurium; regenerable; multifunctional; radical-trapping; hydroperoxide-decomposing; co-antioxidant; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : Antioxidants are widely used to protect organic materials from damages caused by autoxidation, an oxidation process that occurs under normal aerobic conditions. In this thesis, novel multifunctional organoselenium and organotellurium antioxidants were designed, synthesized, and evaluated in search for compounds with better radical-trapping capacity, regenerability, and hydroperoxide-decomposing ability.
