Available in PDF, EPUB and Kindle. Book excerpt: This, the second and final volume of Reactions of Coordinated Ligands, describes the chemistry of ligands bound through non-carbon atoms, and of coordinated carbon dioxide. As before, emphasis is on the underlying mechanisms, which provide a unity of understanding for superficially disparate processes. The wide range of topics covered illustrates well both the versatility and the usefulness of coordination chemistry in the controlled activation of ligands. Looking to the future, carbon dioxide is the feedstock of last resort. The homogeneous reduction of dinitrogen to ammonia now seems unlikely to replace the Haber process, but solution reactions also lead to more complex, varied, and valuable products. Nitrogen monoxide, a "non innocent" ligand, impinges as pollutant and reagent. Its rich chemistry stems from its linked roles as three-electron donor, and as extremely powerful -acceptor. In the hydrolysis and condensation of complexed amides, esters etc. , metals act both as templates and as tunable and poly functional Lewis acids. Here the control of hydrophobic and steric interactions begins to model the subtle mechanisms of biological specificity. Finally, phosphorus and sulfur are imporant both as ligand atoms in themselves, and as anchors for other functionalities. I would like to thank all those who have been involved in the writing and production of this work, and also my colleagues old and new, at Glasgow and the University of North Texas, for their support.

Shilov and published by CRC Press. This book was released on 1997-05-14 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does nature manage to produce reactions from "difficult" substrates? How are stable molecules involved in low-temperature, low-pressure chemical reactions? How can a chemist stop a chemical reaction short of oxidation? Adopting the premise that there is a chemical analog for any naturally occurring enzymatic process, a renowned chemist answers these and other challenging questions in Metal Complexes in Biomimetic Chemical Reactions. Based on reactions this eminent author has studied in the laboratory during his long and distinguished career, this fascinating book explains chemical analogs as they apply to their biological counterparts. This volume covers basic chemical reactions found in nature, including: molecular nitrogen reduction in solution; selective hydrocarbon oxidation (including methane); and photodecomposition of water. Numerous drawings, equations, and structures enhance the text. The importance of chemical reactions lies in their extrapolation to natural processes; once we identify the chemical analog, we can devise ecologically sound alternatives to natural chemical reactions.

Abstract: Abstract of thesis entitled "SYNTHESES, STRUCTURES AND REACTIVITY OF THE GROUP 6 AND 7 METAL COMPLEXES CONTAINING CHELATING NITROGEN DONOR LIGANDS AND METAL-LIGAND MULTIPLE BONDS" submitted by Lee Fu Wa for the degree of Doctor of Philosophy at the University of Hong Kong in September, 1997. ____________________________________________________________________ [Cr(CRMe )Cl ] (CRMe =meso-2,3,7,11,12-pentamethyl-3,7,11,17- 3 2 3 2+ tetraazabicyclo[11.3.1]-heptadeca-1(17),13,15-triene), [Cr(CRMe )Cl(H O)], 3 2 2+ + [Cr(CRMe )Cl(CH CN)] and [Cr(CRMe )(N )(OH)] are prepared. Upon addition 3 3 3 3 2+ 2+ of PhI=O to solutions of [Cr(CRMe )Cl(CH CN)] and [Cr(CRMe )Cl(H O)] 3 3 3 2 respectively in CH CN, the UV-visible absorption spectra of the two mixtures show similar isosbestic spectral changes attributed to the formation of V 2+ [Cr (CRMe )Cl(O)] . Addition of PhP causes the immediate recovery of 3 3 2+ [Cr(CRMe )Cl(CH CN)] as the isosbestic changes are reversed. Irradiation of 3 3 [Cr(CRMe )(N )(OH)] in acetonitrile with UV-visible light gives an azide-free 3 3 product, the FAB-MS of which shows a molecular ion peak indicative of V + + ([Cr (CRMe )(N)]ClO ). The UV-visible spectra of [Cr(CRMe )Cl ], 3 4 3 2 2+ 2+ [Cr(CRMe )Cl(H O)] and [Cr(CRMe )Cl(CH CN)] measured in water are 3 2 3 3 3+ similar to that of [Cr(CRMe )(H O) ] . Results from the conductivity measurement 3 2 2 + 2+ show that in water, [Cr(CRMe )Cl ], [Cr(CRMe )Cl(H O)] and 3 2 3 2 2+ [Cr(CRMe )Cl(CH CN)] behave as 3:1 electrolytes. The species which exists in 3 3 3+ water is likely to be the di-aquo complex [Cr(CRMe )(H O) ] . 3 2 2 2+ 2+ [Cr(CRMe )Cl(H O)] and [Cr(CRMe )Cl(CH CN)] are both found to give a 3 2 3 3 reversible oxidation couple at +1.11 V vs. SCE in aqueous solutions at pH=1 which is assigned to Cr(III)/(IV). iii t + The bis(imido) complexes [(TACN)M(N Bu) Cl] (M=Cr, Mo; TACN=1,4,7-triazacyclononane) and their 1,4,7-trimethyl derivatives are prepared, the crystal structures of which reveal the trans influence of the imido group. These 0 +/0 d species display a quasi-reversible couple at potentials 0.86 - 1.20 V vs. Cp Fe in acetonitrile assignable to a imido ligand-centred oxidation. (Me TACN)Mo(CO), 1,4,7-Tri((S)-2-methylbutyl)-1,4,7-triazacyclononane 3 3 * * * (L ) and L Mo(CO) are synthesized. (Me TACN)Mo(CO) and L Mo(CO) show 3 3 3 3 +/0 reversible oxidation couples at -0.26 V and -0.24 V vs. Cp Fe in CH CN 2 3 I/0 respectively which are assigned to Mo . The comparable electronic effect of * Me TACN and L in this system is therefore implied. 2+ [(Me TACN) Mn (μ-O)(μ-OCOCH ) ] is prepared and found to mediate 3 2 2 3 2 aziridination of styrene, methylstyrene, cis- and trans-stilbene, 1,1-diphenylethene and norbornene by PhI=NTs in CH Cl at 25 C. The nitrene transfer to cis- and 2 2 trans-stilbene is found to be stereoselective to exclusively give the trans-aziridine product. + + [(Me TACN)(CO) M CPh] (M=Mo, W) and [(TACN)(CO) Mo CPh] 3 2 2 are prepared. [(Me TACN)(CO) M CPh] (M=Mo, W) exhibit a reversible 3 2 +/0 reduction couple at -2.15 V vs Fe Cp and an irreversible wave at 0.77 V vs +/0 Fe Cp, which are ascribed to a reduction centred at the phenyl ring and oxidation of the terminal CO respectively.

Download or read book Metal Complexes in Aqueous Solutions written by Arthur E. Martell and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stability constants are fundamental to understanding the behavior of metal ions in aqueous solution. Such understanding is important in a wide variety of areas, such as metal ions in biology, biomedical applications, metal ions in the environment, extraction metallurgy, food chemistry, and metal ions in many industrial processes. In spite of this importance, it appears that many inorganic chemists have lost an appreciation for the importance of stability constants, and the thermodynamic aspects of complex formation, with attention focused over the last thirty years on newer areas, such as organometallic chemistry. This book is an attempt to show the richness of chemistry that can be revealed by stability constants, when measured as part of an overall strategy aimed at understanding the complexing properties of a particular ligand or metal ion. Thus, for example, there are numerous crystal structures of the Li+ ion with crown ethers. What do these indicate to us about the chemistry of Li+ with crown ethers? In fact, most of these crystal structures are in a sense misleading, in that the Li+ ion forms no complexes, or at best very weak complexes, with familiar crown ethers such as l2-crown-4, in any known solvent. Thus, without the stability constants, our understanding of the chemistry of a metal ion with any particular ligand must be regarded as incomplete. In this book we attempt to show how stability constants can reveal factors in ligand design which could not readily be deduced from any other physical technique.
