Cross-Coupling Reactions: A Practical Guide
ISBN: 9783642075766 / Angielski / Miękka / 248 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In 1972, a very powerful catalytic cycle for carbon-carbon bond formation was 2 first discovered by the coupling reaction of Grignard reagents at the sp -carbon. Over the past 30 years, the protocol has been substantially improved and expanded to other coupling reactions of Li, B, N, O, Al, Si, P, S, Cu, Mn, Zn, In, Sn, and Hg compounds. These reactions provided an indispensable and simple methodology for preparative organic chemists. Due to the simplicity and rel- bility in the carbon-carbon, carbon-heteroatom, and carbon-metalloid bo- formations, as well as high efficiency of the catalytic...

Catalysis and Zeolites: Fundamentals and Applications
ISBN: 9783642083471 / Angielski / Miękka / 564 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Zeolites occur in nature and have been known for almost 250 years as alumino silicate minerals. Examples are clinoptilolite, mordenite, offretite, ferrierite, erionite and chabazite. Today, most of these and many other zeolites are of great interest in heterogeneous catalysis, yet their naturally occurring forms are of limited value as catalysts because nature has not optimized their properties for catalytic applications and the naturally occurring zeolites almost always contain undesired impurity phases. It was only with the advent of synthetic zeolites in the period from about 1948 to 1959...

Lanthanides: Chemistry and Use in Organic Synthesis
ISBN: 9783642084195 / Angielski / Miękka / 307 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. While the lanthanides (strictly defined as the 14 elements following lanthanum in the periodic table, but as normally used also include lanthanum itself) have several unique characteristics compared to other elements, their appearance in the history of the development of organometallic chemistry is rather recent. Since the f orbitals are filled gradually from lanthanum ([Xe]4f ) to lutetium ([Xe]4fl4), they are regarded as the f-block elements, which are discriminated from the d-block transition elements. This book was edited as the second volume of "Topics in Organometallic Chemistry",...

Number Theory and the Periodicity of Matter
ISBN: 9789048176922 / Angielski / Miękka / 374 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Of all the great innovations and intellectual achievements of mankind there is nothing that rivals the invention of counting and discovery of the number system. The way in which this discovery led to the development of abstract higher mathematics is the least of its merits, compared to the universal f- cination that the natural numbers hold for all people. Numbers are at the roots of magic, superstition, religion and science. Numerologists can int- pret great historical and cosmicevents, predict thefuture and explain human nature. Better informed, sophisticated people may frown upon and...

Cellular Effects of Heavy Metals
ISBN: 9789400704275 / Angielski / Twarda / 348 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The term heavy metals is used as a group name of toxic metals and metalloids (semimetals) causing contaminations and ecotoxicity. In strict chemical sense the density of heavy metals is higher than 5 g/cm3. From biological point of view as microelements they can be divided into two major groups. a. For their physiological function organisms and cells require essential microelements such as iron, chromium (III), cobalt, copper, manganese, molidenium, zinc. b. The other group of heavy metals is toxic to the health or environment. Of highest concern are the emissions of As, Cd, Co, Cu, Hg,...

P-Stereogenic Ligands in Enantioselective Catalysis
ISBN: 9781849731232 / Angielski / Twarda / 520 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. P-stereogenic ligands were among the first to be used in asymmetric catalysis but synthetic difficulties and prejudices have hampered their development. However, continuous screening for new chiral ligands means that they can no longer be ignored and this rigorous reference source reflects their renaissance. The book is filled with many examples from recent primary literature. The synthetic chemist will easily be able to follow the preparation methods which are accompanied by a description of the challenges and limitations. Those working in homogenous catalysis, and wanting to increase their...

Materials Syntheses: A Practical Guide
ISBN: 9783211999127 / Angielski / Miękka / 228 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Materials syntheses are generally more complex than syntheses of inorganic or organic compounds, and specific characterization methods play a more important role. Materials synthesis protocols often suffer from unclarities, irreproducibility, lack in detail and lack in standards. The need to change this situation is the main motivation for this book. A number of detailed protocols has been collected, ranging from organic polymers to carbonaceous and ceramic materials, from gels to porous and layered materials and from powders and nanoparticles to films. Preparation methods include... Materials syntheses are generally more complex than syntheses of inorganic or organic compounds, and specific characterization methods play a more ... |

Localized to Itinerant Electronic Transition in Perovskite Oxides
ISBN: 9783642086960 / Angielski / Miękka / 239 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Interest in the transition metal oxides with perovskite related structures goes back to the 1950s when the sodium tungsten bronzes NaxWO3 were shown to be metallic [1 ], the system Lal_xSr~MnO3 was found to contain a ferromagnetic conductive phase [2], and La0.sSr0.sCoO3 was reported to be a ferromagnetic metal, but with a peculiar magnetization of 1.5 #a/Co atom [3]. Stoichiometric oxide perovskites have the generic formula AMO3 in which the A site is at the center of a simple cubic array of M sites; the oxide ions form (180 4)) M O M bridges to give an MO3 array of corner shared MO6/2...

N-Heterocyclic Carbenes: From Laboratory Curiosities to Efficient Synthetic Tools
ISBN: 9781849730426 / Angielski / Twarda / 468 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Over the last fifteen years, N-heterocyclic carbenes (NHCs) have mostly been used as ancillary ligands for the preparation of transition metal-based catalysts. Compared to phosphorus-containing ligands, NHCs tend to bind more strongly to metal centres, avoiding the necessity for the use of excess ligand in catalytic reactions. The corresponding complexes are often less sensitive to air and moisture, and have proven remarkably resistant to oxidation. Recent developments in catalysis applications have been facilitated by the availability of carbenes stable enough to be bottled, particularly for...
