  1. 1. New methods for the synthesis of N-heteroaromatics and imines

    Författare :Kenji Kopf; Belén Martín Matute; Joseph P. A. Harrity; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; heterocyclic; heteroaromatic; atropisomer; pyridine; pyrimidine; MOF; amine coupling; catalysis; benzannulation; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis is divided in four chapters, containing the work realised in two universities and has as the aim the synthesis of nitrogen-containing compounds. The first chapter describes the project realised at The University of Sheffield. LÄS MER

  2. 2. Carbohydrate-Functionalized Nanomaterials : Synthesis, Characterization and Biorecognition Studies

    Författare :Na Kong; Mingdi Yan; Joseph J. Barchi Jr; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; carbohydrate; glyconanomaterials; perfluorophenyl azide PFPA ; CuAAC; AAAC; coupling chemistry; 19 F q NMR; lectin; carbon nanomaterials; microwave irradiation; Kemi; Chemistry; Biotechnology; Bioteknologi;

    Sammanfattning : This thesis focuses on the development of carbohydrate coupling chemistry on nanomaterials and their biological activity studies. It is divided into two parts:In part one, two carbohydrate immobilization approaches, based on perfluorophenyl azide (PFPA)-functionalized silica nanoparticles (SNPs), are presented, where the binding affinity of the glyconanoparticles was evaluated through carbohydrate-lectin interaction.

  3. 3. Laccase from a Litter Degrading Fungus: Evaluation for Environmental Applications and Modification of Lignin to a Bioadhesive

    Författare :Victor Ibrahim; Bioteknik; []

    Sammanfattning : Laccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product.

  4. 4. Imine/azo-linked microporous organic polymers : Design, synthesis and applications

    Författare :Chao Xu; Niklas Hedin; Dave Adams; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microporous organic polymers; CO2 capture and separation; post-modification; chemisorption; heterogeneous catalysis; materialkemi; Materials Chemistry;

    Sammanfattning : Microporous organic polymers (MOPs) are porous materials. Owing to their high surface area, tunable pore sizes and high physicochemical stability, they are studied for applications including gas capture and separation and heterogeneous catalysis. In this thesis, a series of imine/azo-linked MOPs were synthesized. LÄS MER

  5. 5. The three-component aza-Baylis-Hillman reaction : development and application

    Författare :Daniela Balan; Hans Adolfsson; Varinder Aggarwal; Stockholms universitet; []

    Sammanfattning : The current thesis presents the optimization and generalization of the Baylis-Hillman reaction applied to in situ generated imines, i.e. a three-component aza- Baylis-Hillman reaction. We found that the title reaction proceeds most efficiently in the presence of a combination of catalysts, i. LÄS MER
