  2. 1. Coordination chemistry of late transition metals with PCP ligands. Synthesis, catalysis and mechanism

    Author : Daniel Olsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organometallic chemistry; Metallorganisk kemi; Organic chemistry; Oorganisk kemi; Inorganic chemistry; Suzuki reaction; Stille reaction; catalysis; cyclometalation; C-H activation; PCP complex; POCOP ligand; PCP ligand; iridium; palladium; platinum;

    Abstract : Abstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. READ MORE

  4. 2. Reactivity of late transition metal complexes towards CO2 and other electrophiles

    Author : Magnus Johnson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2; carbon dioxide; electrophiles; late transition metal complexes; catalysis; halogen bonding; XB; cyclometallation; pincer; organometallic synthesis;

    Abstract : In times when dwindling energy resources is a major long-term problem for sustaining modern infrastructure and technologies, we need to focus on more enduring solutions. A key contribution to this achievement is catalysis. READ MORE

  5. 3. Nickel and iridium pincer complexes with saturated frameworks - synthesis and reactivity

    Author : Klara Jonasson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCP complexes; aliphatic pincer ligands; coordination; cyclometallation; iridium; nickel; organometallic synthesis; CO2 activation; catalysis;

    Abstract : As the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. READ MORE

  6. 4. Aliphatic Polyesters for Soft Tissue Engineering : Development from Conventional Organometallic to Novel Enzymatic Catalysis

    Author : Rajiv Kumar Srivastava; Ann-Christine Albertsson; Stanishaw Penzzek; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aliphatic polyester; 1; 5-dioxepan-2-one; ε-caprolactone; L-lactide; D-lactide; D; L-lactide; enzyme; lipase CA; lipase PS; Polymer chemistry; Polymerkemi;

    Abstract : The development of macromolecules with defined structure and properties, aimed specifically for biomedical applications, has resulted in diverse biodegradable polymers with advanced architectures. Among them, aliphatic polyesters synthesized by ring-opening polymerization (ROP) of lactones and lactides have a leading position due to their good mechanical properties, hydrolyzability and biocompatibility.

  7. 5. Development of New Synthetic Routes to Organoboronates by Catalytic Allylic Substitution and C-H bond Functionalization

    Author : Vilhelm Olsson; Kálmán Szabó; Gary A. Molander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palladium; Iridium; Boron; Catalysis; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis describes the development of new catalytic methods for the synthesis and application of organometallic reagents, mainly focusing on allylboronic acid derivatives. Thus, palladium pincer-complex catalysis has been applied for extending the scope of palladiumcatalyzed borylation reactions in the synthesis of regio- and stereodefined functionalized allylboronic acid derivatives.
