Book excerpt: Compounds of the Transition Elements Involving Metal-Metal Bonds focuses on compounds of the transition elements involving metal-metal bonds. Emphasis is on metal-metal bonds in coordination compounds and organometallic complexes, halides, and oxides. Factors that influence the formation, stability, and properties of such compounds, as well as their application in various fields of chemistry and physics, are discussed. This book is divided into four sections and begins with a classification of metal-metal bonds and some of the physical and chemical methods used to study them, including X-ray crystallography, magnetic susceptibility and electron spin resonance, nuclear spin resonance, Mössbauer measurements, infrared and Raman spectroscopy, visible and ultraviolet spectroscopy, mass spectrometry, electrical conductivity, electrochemistry, and chemical reactivity. Factors influencing the strength of metal-metal bonds in metals and compounds are also examined. The remaining sections deal with metal-metal bonds in coordination compounds and organometallic complexes, halides, and oxides. This monograph will be a useful resource for inorganic chemists.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Examples of late transition metal complexes with amido, alkoxo and sulfido ligands are relatively rare in part due to enhanced reactivity based on nucleophilicity and basicity of the heteroatomic ligand (X). The highly nucleophilic and basic character of formally anionic X ligands coordinated to metal centers with low oxidation states is attributable to the disruption of ligand-to-metal pi-bonding. Examples of common reactivity for these systems include nucleophilic addition reactions, insertions of unsaturated substrates, acid/base chemistry with acidic C-H bonds and C-H activation reactions with aromatic substrates. In addition to fundamental reactivity studies, these complexes also offer opportunities for incorporation into catalytic processes. Late transition metal complexes with non-dative X ligands have been implicated in several C-X bond forming reactions and have been demonstrated to activate non-polar substrates. Thus, in order to advance the understanding of these reactive systems and to exploit the prospects for synthetic applications toward small molecule transformations, further study is warranted. Presented herein is the study of (IPr)Cu(NR2), (IPr)Cu(OR) and (IPr)Cu(SR) {IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene} complexes in the catalytic hydroamination of electron-deficient olefins toward regioselective formation of C-N, C-O and C-S bonds. The substrate scope encompasses alkyl and aryl amines, including primary and secondary variants, as well as alcohols and thiols. Olefins with cyano, acyl, and ester functionalities and vinylarenes are reactive. In a demonstration of potential application, the hydroamination of p-nitrostyrene with N-methylbenzylamine by (IPr)Cu(NHPh) provides a straight-forward single-step route to an anti-arrhythmic agent. Mechanistic studies are consistent with a reaction pathway that involves intermolecular nucleophilic addition of the Cu-amido to free olefin. In an effort to obtain more active catalyst systems that.

This book was released on 2018 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal complexes with pro-radical ligands have received considerable research attention due to their interesting electronic structures, photophysical properties, and applications in catalysis. The relative ordering of metal and ligand frontier orbitals in a complex incorporating pro-radical ligands dictates whether oxidation/reduction occurs at the metal centre or at the ligand. Many metalloenzymes couple redox events at multiple metal centres or between metals and pro-radical ligands to facilitate multielectron chemistry. Owing to the simplicity of the active sites, many structural and functional models have been studied. One class of pro-radical ligand that has been investigated extensively are bis-imine bis-phenoxide ligands (i.e. salen) due to their highly modular syntheses. In this thesis, projects related to the synthesis, electronic structure, and reactivity of mono and bimetallic complexes incorporating the salen framework are explored. Chapter 2 presents a systematic investigation of the effects of geometry on the electronic structure of four bis-oxidized bimetallic Ni salen species. The tunability of their intense intervalence charge transfer (IVCT) transitions in the near infrared (NIR) by nearly 400 nm due to exciton coupling in the excited states is described. For the first time, this study demonstrates the applicability of exciton coupling to ligand radical systems absorbing in the NIR region. Chapter 3 investigates the ground-state electronic structure of a bis-oxidized Co dimer. Enhanced metal participation to the singly occupied molecular orbitals results in both high spin Co(III) and Co(II)-L• character in the ground state, and no observable band splitting in the NIR due to exciton coupling. Finally, Chapter 4 describes a series of oxidized nitridomanganese(V) salen complexes with different para ring substituents (R = CF3, tBu, and NMe2), demonstrating that nitride activation is dictated by remote ligand electronics. Upon one-electron oxidation, electron deficient ligands afford a Mn(VI) species and nitride activation, whereas an electron-rich ligand results in ligand based oxidation and resistance to N coupling of the nitrides. This study highlights the alternative reactivity pathways that pro-radical ligands impose on metal complexes and represents a key step in the use of NH3 as a hydrogen storage medium. The results presented herein provide a starting point for further efforts in reactivity with the salen platform.

This book was released on 2016 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: C(sp3)-N bond formation is a potential high value reaction in transition metal catalysis, however, only a handful of examples of this fundamental coupling reaction step have been reported. Presented in this thesis are new efforts to promote this challenging reaction. Group 9 and 10 metals bound by the pincer ligands Pybox and PCP, respectively, were initially investigated. Evidence suggests the Ir-Et complex ([(dmPybox)Ir(Et)(OAc)][PF6] (12)) undergoes a [Beta]-H deprotonation, similar to an E2 type elimination in organic chemistry, rather than the desired SN2 nucleophilic attack. Use of strong nucleophiles, i.e. sulfur nucleophiles, resulted in the ring opening of the pybox ligand. Ir-Et complexes bound by the MeBPA ligand ([(MeBPA)Ir(OOCR)Et][PF6] (20 and 21)), however, did undergo the desired reaction to form C-N bonds upon reaction with neutral nitrogen nucleophiles. A computational investigation of the mechanism revealed that rather than the direct attack at the Ir-Et (generally observed for high valent Pd and Pt) the complex first undergoes [Beta]-hydrogen elimination to form an Ir ethylene complex. Nucleophilic attack by amine at the olefin then forms the C-N bond. In the final chapter the synthesis and characterization of new a new Rh-Me complex ((DPEphos)RhMe(I)2 (25)), which undergoes C(sp3)-I reductive elimination, is described. A kinetic investigation of the mechanism indicated two competing mechanisms involving SN2 attack by iodide at both cationic and neutral Rh-Me species. The demonstration of bond formation via nucleophilic attack at the Rh-Me allowed for the room temperature functionalization of the methyl ligand with both nitrogen and sulfur nucleophiles.
