Download or read book Activation and Catalytic Reactions of Saturated Hydrocarbons in the Presence of Metal Complexes written by A.E. Shilov and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: hemistry is the science about breaking and forming of bonds between atoms. One of the most important processes for organic chemistry is breaking bonds C–H, as well as C–C in various compounds, and primarily, in hydrocarbons. Among hydrocarbons, saturated hydrocarbons, alkanes (methane, ethane, propane, hexane etc. ), are especially attractive as substrates for chemical transformations. This is because, on the one hand, alkanes are the main constituents of oil and natural gas, and consequently are the principal feedstocks for chemical industry. On the other hand, these substances are known to be the less reactive organic compounds. Saturated hydrocarbons may be called the “noble gases of organic chemistry” and, if so, the first representative of their family – methane – may be compared with extremely inert helium. As in all comparisons, this parallel between noble gases and alkanes is not fully accurate. Indeed the transformations of alkanes, including methane, have been known for a long time. These reactions involve the interaction with molecular oxygen from air (burning – the main source of energy!), as well as some mutual interconversions of saturated and unsaturated hydrocarbons. However, all these transformations occur at elevated temperatures (higher than 300–500 °C) and are usually characterized by a lack of selectivity. The conversion of alkanes into carbon dioxide and water during burning is an extremely valuable process – but not from a chemist viewpoint.

This book was released on 2018-03-07 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2018 in the subject Chemistry - Anorganic Chemistry, grade: 10, , language: English, abstract: Nanoscience is the study of phenomena exhibited by materials at atomic, molecular and macromolecular levels, of dimensions ranging from a few nanometres to less than a hundred nanometres. In chemistry, this size range has been associated with colloids, micelles, polymer molecules and similar structures. In physical and electrical engineering, nanoscience is often associated with quantum behaviour, and electron behaviour in nanoscale structures. The area of research in the field of nanotechnology is as diverse as physics, chemistry, material science, microbiology, biochemistry and also molecular biology. The interface of nanotechnology in combination with biotechnology and biomedical engineering has emerged with the use of nanoscale structures in diagnosis, gene sequencing, and drug delivery. Nanoparticles have attracted great interest in recent years because of their unique chemical and physical properties, which are different from those of either the bulk materials or single atoms. Nanostructure materials have potential applications in ceramics, optoelectronics and catalysis. Research on the synthesis of nanomaterials using metal complexes as precursors have been less reported. Application of metal complexes as precursors may be helpful to control the physical properties of metal nanoparticles. In the last few years, researchers have characterized the tunable properties by altering the nanostructure size, shape, and chemical composition and have developed reproducible strategies to make nanostructures of desired properties. It has been already proved that by controlling the size of the particle and manipulating surface structures of the semiconductor materials, the electronic, magnetic, mechanical, and chemical properties can be modified to suit a wide range of device application in many fields. The present book deals with the synthesis of Schiff base complexes of Cd(II), Zn(II) and Hg(II) with different sulphur containing ligand and preparation of metal sulphide nanoparticle by the thermal decomposition of complex precursor. During this academic journey four new sulphur containing ligands and their thirty complexes were synthesized. These ligands and complexes were characterized by spectroscopic methods like UV-Vis, FT-IR, 1H-NMR, 13C-NMR, 2D-NMR, FAB-MS / ESI-Ms spectra.

Download or read book Cisplatin written by Bernhard Lippert and published by John Wiley & Sons. This book was released on 1999 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: 30 years after its discovery as an antitumor agent, cisplatin represents today one of the most successful drugs in chemotherapy. This book is intended to reminisce this event, to take inventory, and to point out new lines of development in this field. Divided in 6 sections and 22 chapters, the book provides an up-to-date account on topics such as - the chemistry and biochemistry of cisplatin, - the clinical status of Pt anticancer drugs, - the impact of cisplatin on inorganic and coordination chemistry, - new developments in drug design, testing and delivery. It also includes a chapter describing the historical development of the discovery of cisplatin. The ultimate question - How does cisplatin kill a cell? - is yet to be answered, but there are now new links suggesting how Pt binding to DNA may trigger a cascade of cellular reactions that eventually result in apoptosis. p53 and a series of damage recognition proteins of the HMG-domain family appear to be involved. The book addresses the problem of mutagenicity of Pt drugs and raises the question of the possible relevance of the minor DNA adducts, e.g. of interstrand cross-links, and the possible use of trans-(NH3)2Pt(II)-modified oligonucleotides in antisense and antigene strategies. Our present understanding of reactions of cisplatin with DNA is based upon numerous model studies (from isolated model nucleobases to short DNA fragments) and application of a large body of spectroscopic and other physico-chemical techniques. Thanks to these efforts there is presently no other metal ion whose reactions with nucleic acids are better understood than Pt. In a series of chapters, basic studies on the interactions of Pt electrophiles with nucleobases, oligonucleotides, DNA, amino acids, peptides and proteins are reported, which use, among others, sophisticated NMR techniques or X-ray crystallography, to get remarkable understanding of details on such reactions. Reactivity of cisplatin, once bound to DNA and formerly believed to be inert enough to stay, is an emerging phenomenon. It has (not yet) widely been studied but is potentially extremely important. Medicinal bioinorganic chemistry - the role of metal compounds in medicine - has received an enormous boost from cisplatin, and so has bioinorganic chemistry as a whole. There is hardly a better example than cisplatin to demonstrate what bioinorganic chemistry is all about: The marriage between classic inorganic (coordination) chemistry and the other life sciences - medicine, pharmacy, biology, biochemistry. Cisplatin has left its mark also on areas that are generally considered largely inorganic. The subject of mixed-valance Pt compounds is an example: From the sleeping beauty it made its way to the headlines of scientific journals, thanks to a class of novel Pt antitumor agents, the so-called "platinum pyrimidine blues". In the aftermath diplatinum (III) compounds were recognized and studies in large numbers, and now an organometalic chemistry of these diplatinum (III) species is beginning to emerge. The final section of the book is concerned with new developments such as novel di- and trinuclear Pt(II) drugs with DNA binding properties different from those of cisplatin, with orally active Pt(IV) drugs which are presently in clinical studies, and with attempts to modify combinatorial chemistry in such a way that it may become applicable to fast screening of Pt antitumor drugs. The potential of including computational methods in solving questions of Pt-DNA interactions is critically dealt with in the concluding chapter.

This book was released on 2016-10-21 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience.

Download or read book Quinoxalines written by Vakhid A. Mamedov and published by Springer. This book was released on 2016-04-26 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the fundamental aspects of quinoxaline chemistry: synthesis, reactions, mechanisms, structure, properties, and uses. The first four chapters present a survey of the developments in quinoxaline chemistry since the publication of the monograph on “Condensed Pyrazines” by Cheeseman and Cookson in 1979. These chapters give comprehensive coverage of all the methods of the synthesis of quinoxalines and the important quinoxaline-containing ring systems such as thiazolo[3,4-a]-, pyrrolo[1,2-a]-, and imidazo[1,5-a]quinoxalines. Chapter five describes many new methods for the construction of quinoxaline macrocycles, which are important in applications such as optical devices and materials. The final chapter reviews all previously known rearrangements of heterocyclic systems that lead to benzimidazole derivatives. Mamedov critically analyses these transformations to reveal a novel acid-catalyzed rearrangement of quinoxalinones giving 2-heteroarylbenzimidazoles and 1-heteroarylbenzimidazolones in the presence of nucleophilic reactants (MAMEDOV Heterocycle Rearrangement). This book is of interest to researchers in the fields of heterocyclic and synthetic organic chemistry.
