  1. 1. Organic Heavy Group 14 Element Compounds : A Study of Their Chemical Bonding Properties Directed Towards Applications as Molecular Wires and in Synthesis

    Author : Julius Tibbelin; Henrik Ottosson; Christoph Marschner; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Silicon; Group 14 Elements; Silenes; Conjugation; Chemical Bonding; Electronic Structure; Protecting Group Chemistry; Physical organic chemistry; Fysikalisk organisk kemi; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The research described herein includes synthesis, spectroscopy, and quantum chemical calculations with focus on the characteristic properties of compounds with bonds between carbon and the heavier Group 14 elements.The chapters based on the first four papers concern σ- and σ/π-conjugated compounds, although the focus of the first paper is on ring strain of bicyclo[1.

  2. 2. Synthesis of Organic Compounds for Nuclide Therapy : Derivatives of Carboranes, 9-Aminoacridine and Anthracyclines

    Author : Senait Ghirmai; Stefan Sjöberg; Vladimir Tolmachev; Tor Kihlberg; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; 9-Aminoacridin; Carborane; Daunorubicin; Doxorubicin; BNCT; Iodine-125; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : This thesis addresses the synthesis of organic compounds, some of them are derivatives of compounds with DNA binding properties, for potential use in targeted nuclide therapy. The compounds synthesized therefore also need to contain potent nuclides. READ MORE

  3. 3. Hyperconjugation in Group 14 Organic Compounds : Design and Property Investigations

    Author : Aleksandra Denisova; Henrik Ottosson; Thomas Müller; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 1; 4-disilacyclohexa-2; 5-diene; aromaticity; computational chemistry; conjugation; cross-hyperconjugation; hyperconjugation; group 14 elements; organosilicon chemistry; silole;

    Abstract : Nowadays π-conjugated molecules are widely used as materials for devices in organic and molecular electronics. This is due to the ability of such molecules to conduct electricity. However, π-conjugation leads to molecular rigidness and associated lower solubility, which limits possible applications. READ MORE

  4. 4. BIOACTIVE ORGANOMETALLIC COMPOUNDS

    Author : Haris Bjelosevic; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biological; kinetic; gold; platinum; bioactive; phosphine; ruthenocene; Ferrocene;

    Abstract : Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. READ MORE

  5. 5. Production and transformation of organic compounds from renewable feedstock : Catalytic approaches

    Author : Elena Subbotina; Joseph Samec; Pieter Bruijnincx; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Lignin; biomass; lignin-first; catalytic fractionation; flow reactors; dibenzodioxocin; silanes; zeolites; visible light photocatalysis; dearomatization; spirolactones; Organic Chemistry; organisk kemi;

    Abstract : This thesis is focused on the development of strategies for lignocellulosic biomass valorization. The thesis consists of two parts.The first part of the presented work is related to the catalytic fractionation of biomass (lignin-first approach) and the production of monomeric compounds from lignocellulose.
