Baffled by benzines? Confused by carboxylic acids? Here's the help you need—in plain English!
Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts – with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage.
The product emphasises a sequential, building-block approach to the subject gained through the author’s previous writings (particularly Extractive Metallurgy of Copper in four editions) and extensive experience. Due to the multiple metals involved and because each metal originates in several types of ore – e.g. tropical ores and arctic ores this necessitates a multi-contributor work drawing from multiple networks and both engineering and science.Synthesizes detailed review of the fundamental chemistry and physics of extractive metallurgy with practical lessons from industrial consultancies at the leading international plantsDiscusses Nickel, Cobalt and Platinum Group Metals for the first time in one bookReviews extraction of multiple metals from the same tropical or arctic oreIndustrial, international and multidisciplinary focus on current standards of production supports best practice use of industrial resources
The author has drawn on his own research and the current literature to ensure that appropriate attention is given to topics across the range of modern organic chemistry. The text is unique in its inclusion of a chapter on reactions mediated or catalyzed by transition metals, an area in which mechanistic understanding is now essential. Relatively new topics such as olefin metathesis and cycloaromatization are covered without giving short shrift to more traditional areas such as carbonyl chemistry. The text assumes a basic knowledge of organic chemistry. It can be used either in a formal course or by students working on their own, and will be particularly useful for graduate students studying for qualifying examinations. It will also be useful to students and researchers in biochemistry, pharmacology, and inorganic chemistry.
"This is an excellent and well-presented work.... The author ... has succeeded well in treating the central ideas of reactivity and selectivity in an integrated whole. The clear style of writing, the well chosen examples, and the ... concise summaries of the main points provided at the end of each chapter should enable the reader to easily consolidate what has been learned.... The book is indeed a little work of art."
-- Jens Hartung, Angewandte Chemie International Edition
"I have taught a one-credit course with this book for three years, and, uniformly, the students have rated this book highly for its clarity and for the scope of the problems. ... This book does an excellent job at its stated goal: 'to teach students to come up with reasonable mechanisms for reactions they have never seen before.'"
-- Amy Howell, Synthesis
"I have just finished my first year of graduate studies in organic chemistry at Duke University. I just wanted to let you know how much your book got me through the past year of course work.... When it came to mechanisms, I found the clarity and thoroughness I needed only in your book. It was impressive how you were able to present so much information in a clear and comprehensive manner yet keep the book so manageable in size. In addition to the text, I also was able to benefit from the problems.... Great practice!! The on-line answers are much better than looking up answers by reference.... I am reading it again this summer in preparation for my preliminary exam next spring."
-- David Gooden

The aim of the book is twofold. Firstly, to reveal to the reader the combined use of different spectroscopic data, to facilitate an insight into the structure and conformational properties of any new piperidine derivative. Secondly, to establish a consistent link between conformation and reactivity for a variety of piperidine derivatives. Such a bridge is a key step for stereocontrol when dealing with the application of piperidine derivatives as synthetic intermediates. The book is conceived so that most of the information comes from visual inspection of the very abundant graphic material. An exhaustive subject index of more than 450 entries is also included.
