  2. 1. Synthesis of Novel Chiral Bicyclic Ligands and their Application in Iridium-Catalyzed Reactions

    Author : Anna Trifonova; Pher G. Andersson; Guy Lloyd-Jones; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; asymmetric catalysis; Diels-Alder reaction; transfer hydrogenation; hydrogenation; amino-oxazoline; phosphine-oxazoline; imine; olefin; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : The synthesis of 2-aza-norborane derivatives is presented. The use of these compounds in preparation of Ir catalysts for asymmetric hydrogenations is described. The evaluation and optimization of the catalysts as well as the mechanistic aspects of the catalytic process are discussed. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Catalysis in Dynamic Systems: Control within Molecular Reaction Networks

    Author : Fredrik Schaufelberger; Olof Ramström; Leonard Prins; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; systems chemistry; dynamic covalent chemistry; catalyst screening; reaction networks; organocatalysis; imine exchange; combinatorial chemistry; dynamic systemic resolution; feedback; error-correction; Morita-Baylis-Hillman reaction; C-H activation; H-bond catalysis; transamination; Kemi; Chemistry;

    Abstract : Life as we know it is based on complex networks of biochemical reactions that constantly interact within large dynamic systems. The field of systems chemistry uses chemical models to study how reaction networks – and thereby life – function on a molecular level. READ MORE

  6. 4. Responsive Molecular Systems through Dynamic Covalent Chemistry

    Author : Antanas Karalius; Zoltan Szabo; Stefan Matile; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stimuli-responsiveness; dynamic covalent reactions; systems chemistry; constitutional dynamics; non-equilibrium systems; nitroaldol reaction; dynamers; reversible polymerization; boronate ester; imine ligand; metal coordination; self–assembly; emergent properties; network topology.; stimuli-responsivitet; dynamiska kovalenta reaktioner; systemkemi; konstitutionell dynamik; icke-jämviktssystem; nitroaldolreaktion; dynamerer; reversibel polymerisation; boronester; iminligand; metallkoordination; själv-organisation; emergenta egenskaper; nätverkstopologi.; Kemi; Chemistry;

    Abstract : Nature tends to inspire research in chemistry. Systems that emerge from molecules interacting via reaction networks is something that life has mastered over the course of evolution in order to produce complexity. Dynamic reactions are key in systems chemistry, where reaction networks give rise to complex, emergent behavior. READ MORE

  7. 5. New Methods for the Synthesis of 3-Substituted 1-Indanones : A Palladium-Catalyzed Approach

    Author : Anna Arefalk; Anders Hallberg; Mats Larhed; Juan Carlos Carretero; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Heck; palladium; indanone; annulation; microwave heating; triflate; sulfinyl imine; HIV-1 protease inhibitor; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : In medicinal chemistry, there is a constant need for new preparative methods, both to make the synthesis process more effective, and to increase the accessibility to a wide variety of compounds. A number of different approaches can be used to attain these goals. READ MORE
