1. 1. Iron Carbonyl Mediated Parallel Synthesis

   Författare :Henrik Gradén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dienyl; scavenger; solid phase; galectin inhibitor; oseltamivir; iron carbonyl complex; polymer bound reagent; cation; linker; parallel synthesis; active ester;

   Sammanfattning : This thesis describes the examination and development of cationic iron carbonyl complexes for use in parallel synthesis both in solution phase and on solid phase. A solution phase methodology for carbon-carbon and carbon-heteroatom formation, utilizing polymer bound reagents and scavengers and amenable for automation has been successfully developed. LÄS MER

3. 2. Iron Carbonyl Clusters as Proton Reduction Catalysts

   Författare :Ahibur Rahaman; Kemisk fysik; []
   Nyckelord :iron-only hydrogenase; phosphine-substitution; electrocatalysis; proton reduction;

   Sammanfattning : Abstract – The mixed-valence triiron complexes [Fe3(CO)7-x(PPh3)x(µ-edt)2] (x = 0, 1, 2; edt = SCH2CH2S) and [Fe3(CO)5(κ2-diphosphine)(µ-edt)2] (diphosphine = dppv, dppe, dppb, dppn) have been prepared and structurally characterized. In comparison to the diiron complex [Fe2(CO)6(µ-edt)], [Fe3(CO)7(µ-edt)2] catalyzes proton reduction at 0. LÄS MER

4. 3. Surface reactions in aqueous suspensions of fluorapatite and iron oxides

   Författare :Mathias Jarlbring; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : The main objectives have been to study and model surface reactions of aqueous suspen-sions of minerals with relevance to the dephosphorization of iron oxides by reverse froth flotation. Synthetic hematite, maghemite and fluorapatite in colloidal forms were prepared and thoroughly characterized using XRD, SEM, BET, FT-IR and FT-Raman. LÄS MER

5. 4. Structure, dynamics and reactivity of low-oxidation state iron complexes in solution studied by ab initio molecular dynamics simulations and advanced quantum chemistry calculations

   Författare :Michael R. Coates; Michael Odelius; Bo Durbeej; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

   Sammanfattning : Third row (3d) metals, such as iron have become a candidate for a broad class of photocatalysts that have a large abundance on Earth and a low toxicity to humans and the environment. Unlike many commonly used photocatalysts that contain expensive precious metals, iron is cheap. LÄS MER

7. 5. Studies of second coordination sphere effects and metal variations on [FeFe]-hydrogenase mimics

   Författare :Holly J. Redman; Gustav Berggren; Pickett Chris; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogenases; synthesis; inorganic chemistry; molecular biomimetics; spectroscopy; FTIR; cyclic voltammetry; catalysis; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

   Sammanfattning : Mitigation of climate change motivates researchers to explore hydrogen as a potential energy carrier. Unfortunately, widespread use of hydrogen as an energy carrier is limited by numerous challenges in its production, including high energy consumption; high economic cost; current reliance on rare metals such as platinum.
