Abstract: Diphosphines have taken on a dominant role as supporting ligands in transition-metal chemistry. Here, we describe complexes of the type [Cp*Fe(diphosphine)(X)] (X = Cl, H) where for diphosphine = 1,2-bis(di-allylphosphino)ethane (tape), a Lewis-acidic secondary coordination… read more here.

DOI: 10.1021/acs.inorgchem.8b00032
Abstract: Metal complexes composed of redox-active pyridinediimine (PDI) ligands are capable of forming ligand-centered radicals. In this Forum article, we demonstrate that integration of these types of redox-active sites with bioinspired secondary coordination sphere motifs produce… read more here.

DOI: 10.1021/acscatal.8b04740
Abstract: A series of mannose-templated microgels with immobilized catalytic sites and catalysis-supporting co-monomers was synthesized and evaluated for catalytic hydrolyses of glycosidic bonds. Interactions of the secondary coordination sphere around the catalytic center were implemented between… read more here.

DOI: 10.1021/acschembio.7b00016
Abstract: Polysaccharide monooxygenases (PMOs) are secreted metalloenzymes that catalyze the oxidative degradation of polysaccharides in a copper-, oxygen-, and reductant-dependent manner. Cellulose-active fungal PMOs degrade cellulosic substrates to be utilized as a carbon source for fungal… read more here.
