Variable character of O—O and M—O bonding in side-on (η2) 1:1 metal complexes of O2
The structures and the O—O and M—O bonding characters of a series of reported side-on (η2) 1:1 metal complexes of O2 are analyzed by using density functional theory calculations. Comparison of theExpand
Binding and activation of small molecules by three-coordinate Cr(I).
[(i-Pr2Ph)2nacnacCr]2(μ-η2:η2-N2) (2) has been prepared and structurally characterized; it contains a bridging side-on bonded dinitrogen ligand with a N−N distance of 1.249(5) A. Reactions of thisExpand
New complexes of chromium(III) containing organic π-radical ligands: an experimental and density functional theory study.
The electronic structures of a series of chromium complexes 1-7 have been experimentally investigated using a combination of X-ray crystallography, magneto- and electrochemistry, and Cr K-edge X-rayExpand
Chromium mediated reductive coupling of isonitrile forms unusual heterocycles.
The quintuply bonded α-diimine chromium dimer [(H)L(iPr)Cr]2 reductively couples cyclohexyl isocyanide to produce various novel nitrogen heterocycles. Tetramerization yielded, inter alia, theExpand

The metal-catalyzed polymerization of simple olefins, such as ethylene and propylene, has been one of the transformational discoveries in chemistry of the 20th century. It is difficult to imagineExpand
Synthesis and Structure of a Chromium(III) Complex Supported by a β-diketiminate and an Enediolate Ligand
The complex (bis(2,6-diisopropylphenyl)pentane-2,4-ketiminato)(9,10-dihydro-9,10-(ethenediolato)anthracene)(tetrahydrofuran)chromium(III) (1) has been synthesized and structurally characterized.Expand
Chromium: Organometallic Chemistry
Starting with Hein's investigation of the reaction of CrCl3 with PhMgBr in the beginning of the twentieth century, chromium organometallic chemistry is now marked by an ever increasing diversity ofExpand
C-H bond activations by metal oxo compounds.
In an era dominated by the utilization of hydrocarbon mixtures (i.e., oil and natural gas) as feedstocks for the chemical industry, the functionalization of C-H bonds, particularly in a selectiveExpand
Catalytic significance of the specificity of divalent cations as KS* and kcat* cofactors for secreted phospholipase A2.
Calcium is required for the substrate binding and for the chemical step of the interfacial catalytic turnover cycle of pancreatic phospholipase A2 (PLA2), but not for the binding of the enzyme to theExpand
The shortest metal-metal bond yet: molecular and electronic structure of a dinuclear chromium diazadiene complex.
Reduction of a diazadiene chromium halide complex, [(HLiPr)Cr(μ-Cl)]2 (1, HLiPr = bis(2,6-diisopropylphenyl)diazadiene), with KC8 gave a diamagnetic, bimetallic complex, (HLiPr)2Cr2 (2). Complex 2Expand
