Advances in Metal-Mediated Bond Activation: From Unusual Bonding
Motifs to Applications in Catalysis
The metal-mediated activation of typically unreactive bonds provides opportunities for the development of new stoichiometric and/or catalytic substrate transformations. This symposium focuses on recent advances in metal-mediated bond activation, including the development of new ancillary ligand architectures that can support mono- or polynuclear complexes, and which exhibit novel reactivity patterns by virtue of their unique construction. Properties subject to control include ligand-induced electrophilic or oxidative character, and reducing power or nucleophilicity, including reactivity across a metal/ligand single or multiple bond. This symposium will focus on how ligand choice influences both the bond-cleavage and bond-formation by a transition metal complex, with special focus on the strong and sometimes inert single or multiple bonds between any pair of the atoms B, C, N, O and F. Applications include fine chemical synthesis, homogeneous catalysis and also chemical sensing and gaseous molecule storage. The symposium will draw from examples in coordination, organometallic and bioinorganic chemistry, as well as reactions of O2, H2 and H2O which relate to energy storage and generation. Ligand delocalization of electron density in electron rich or electron poor metal situations will also be included, together with how these "redox storage" strategies influence reactivity towards substrates.
