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

    University dissertation from Department of Chemistry, Lund University

    Author : Biswanath Das; [2013]
    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
