  4. 22. Hydrolytic and oxidative catalytic activities of bio-inspired dinuclear metal complexes

    Author : Biswanath Das; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioinorganic Chemistry; Metalloenzymes; Catalyst; Transition states; Phosphoesterase;

    Abstract : A number of homo- and heterodinuclear complexes have been synthesized as structural and functional models for the the active sites of phosphoesterases and soluble methane monooxygenases. The complexes are based on four new dinucleating ligands containing a central, potentially bridging, phenolate moiety. READ MORE

  6. 24. Carbenes: The Gathering : Photophysics of Transition Metal Carbene Complexes

    Author : Nidhi Kaul; Leif Hammarström; James K. McCusker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photophysics; time-resolved spectroscopy; transition-metal complexes; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Abstract : This thesis explores the photophysics of some transition-metal complexes (TMCs) which utilize N-heterocyclic carbenes as ligands. After a historical interlude which traces the development of the broader field of transition metal complexes and their photophysical investigations, there is an overview of theoretical concepts and the spectroscopic methods employed.

  7. 25. Investigation of Coordination Modes of Organosulfur Ligands to osmium and Rhodium Carbonyl Clusters- Possible Relevance to Hydrodesulfurization Reactions

    Author : Nitsa Kiriakidou-Kazemifar; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thioethers; thiols; HDS processes; organosulfur compounds; polynuclear metal complexes; Metallorganisk kemi; Organometallic chemistry; thiophenes;

    Abstract : The coordination and fundamental transformations of organosulfur compounds to polynuclear metal complexes has been studied as models for possible surface species in industrial HDS processes. Reactions between [Os3(CO)11(NCMe)] and various thiols have been studied by UV-Vis, IR and NMR spectroscopy and all experimental findings indicate that the reactions proceed via a two-step consecutive process involving the intermediate [Os3(CO)11(RSH)], which contains an agostic Os-H-S interaction, and which leads to the formation of the final product [Os3(CO)10(m-H)(m-SR)].
