The Earth’s most abundant naturally occurring oxidant is—frankly—poorly understood and controlled, and thus underused. Copper-based enzyme metallocofactors are ubiquitous to the efficient consumption of dioxygen by all domains of...

Soc. , Article ASAP DOI:  10.1021/jacs.5b04738 Publication Date (Web): June 3, 2015 Copyright © 2015 American Chemical Society http://pubs.acs.org/doi/abs/10.1021/jacs.5b04738 Abstract All known nitrogenase cofactors are rich in both sulfur and iron and are presumed capable of binding and reducing N 2 . Nonetheless, synthetic examples of transition metal model complexes that bind N 2  and also feature sulfur donor ligands remain scarce. We report herein an unusual series of low-valent diiron complexes featuring thiolate and dinitrogen ligands. A new binucleating ligand scaffold is introduced that supports an Fe(μ-SAr)Fe diiron subunit that coordinates dinitrogen (N 2 -Fe(μ-SAr)Fe-N 2 ) across at least three oxidation states (Fe II Fe II , Fe II ...

Angewandte Chemie International Edition  by Christoph A. Rettenmeier, Hubert Wadepohl, Lutz H. Gade  /   5d   //   keep unread  //   hide   //   preview Abstract Pincer-stabilized nickel(I) complexes readily react with molecular oxygen to form dinuclear 1,2-μ-peroxo-bridged nickel(II) complexes, which are the major components of a dynamic equilibrium with the corresponding mononuclear superoxo species. The peroxo complexes further react with hydrogen peroxide to give the corresponding nickel(II) hydroperoxides. One of these hitherto elusive species was characterized by X-ray diffraction for the first time [O–O bond length: 1.492(2) Å]. Pincer-stabilized nickel(I) complexes  readily react with molecular oxygen to form dinuclear 1,2-μ-peroxo-bridged nickel(II) complexes, which are the major components of a dynamic equilibrium with the corresponding mononuclear superoxo species.

A series of dinuclear and tetranuclear first-row transition metal complexes were synthesized with the dinucleating ligand 2,7-bis(di(2-pyridyl)fluoromethyl)-1,8-naphthyridine (DPFN). The coordination pocket and rigidity of the DPFN ligand enforces pseudo-octahedral geometries about the metal centers that contain chloro, hydroxo, and aqua bridging ligands forming a “diamond” shaped configuration with metal–metal distances varying from 2.7826(5) to 3.2410(11) Å. Each metal center in the dinuclear complexes has an additional open coordination site that accommodates terminal ligands in a  syn  geometry of particular interest in catalyst design. The complexes are characterized by electronic spectroscopy, electrochemistry and potentiometric titration methods. http://pubs.rsc.org/en/Content/ArticleLanding/2014/DT/C4DT02727B#!divAbstract
