Topics In Enantioselective Catalysis: Recent Achievements And Future Challenges by Angela Marinetti Pdf

This book illustrates the broad field of enantioselective catalysis by highlighting a few topics, out of myriads, with the double aim to typify selected synthetic achievements and future challenges. Eleven research groups have highlighted topics of interest in either organo- or organometallic catalysis, related to their own expertise. For mature fields, these short chapters, far from being exhaustive, show updated overviews including major recent advances and disclose a few prospects. Other chapters focus on upcoming topics in enantioselective catalysis, i.e. on classes of reactions or families of catalysts that are expected to provide appealing synthetic tools when suitably mastered. For all these areas, recent studies demonstrate highly promising perspectives.

Electrochemistry Of Metalloporphyrins by Karl M Kadish,W Ryan Osterloh,Eric Van Caemelbecke Pdf

This book is part of a series of ongoing volumes in the Series on Chemistry, Energy and the Environment, edited by Karl Kadish and Roger Guilard. The current volume on Electrochemistry of Metalloporphyrins covers all aspects of porphyrin electrochemistry in nonaqueous media and should be of benefit and interest to beginning graduate students as well as experienced researchers in many fields of porphyrin chemistry where electrochemistry is known to play a key role in influencing properties of the compounds as well as mechanisms and biological functions. The first half of the book is aimed at non-experts in the field of electrochemistry who would like to begin studies on porphyrin electrochemistry or understand the literature on porphyrin electrochemistry and this is then followed by detailed examples of how changes in the central metal ion of a given metalloporphyrin will affect its redox properties. The scope of the work covers the period in the literature between the mid-1960s and mid-2022 and expands greatly upon several earlier reviews by the senior author which are no longer in print and were never accessible in electronic form. This is the only book of its kind in the field which covers the basic electrochemistry of metalloporphyrins as well as describes the published data as a function of the central metal ion, considering all elements in the periodic table.

Synthesis And Applications In Chemistry And Materials (In 4 Volumes) by Armando J L Pombeiro,Kamran T Mahmudov,Maria De Fatima Costa Guedes Da Silva Pdf

Chemistry and Material Sciences naturally depend greatly on Synthesis as the initial stage for the existence of compounds and materials with desired behaviors, within the overall streamline of Design/Synthesis — Properties — Application/Function, and their relations. Such a general approach is of a too wide scope to be properly treated in a single set of publications, but this one on 'Synthesis and Applications in Chemistry and Materials' restricts itself by aiming to show the strength and international character of the current research in synthetic chemistry that is being developed in Portugal or abroad by teams that cooperate with this country. Hence, it gathers representative contributions of main Portuguese research groups and foreign collaborating ones. Nevertheless, the topic should be understood in a wide sense, being open to types of studies with significance on sustainable synthesis and applications in chemistry, materials and/or related sciences.

New Trends in Asymmetric Catalysis by Giorgio Della Sala Pdf

The synthesis of enantiopure organic compounds is a key issue for several applications in pharmacology, food chemistry, agricultural chemistry, perfumery, materials science and other industrial sectors. Nowadays, asymmetric catalysis is undoubtedly the most important tool to achieve this goal. This technology, in fact, enables the production of large amounts of enantiomerically enriched compounds, employing relatively small quantities of chiral enantiopure catalysts, which is exactly what is accomplished by enzymes in nature. Since the pioneering works of Noyori, Knowles and Sharpless, which later earned them the Nobel Prize in Chemistry, asymmetric catalysis has experienced a rapid and relentless development in the last fifty years. The tremendous expansion of enantioselective transformations, the design of novel and more efficient organometallic and organic catalysts, the development of sophisticated bioreactors and cell factories, are just some of the elements responsible for such growth. However, new challenges of asymmetric catalysis are devoted to enhancing the process’s sustainability, by the introduction of recyclable and low-cost catalysts, and the use of renewable starting materials and energy source. This book provides an overview of some of these development directions and comprises a collection of review papers and a research article authored by renowned researchers actively involved in this field. The topics covered by the review papers are photoredox-catalyzed reactions of imines, asymmetric catalytic electrosynthesis, cooperative catalysis of chiral N-heterocyclic carbenes and Lewis acid, and asymmetric ring-opening reactions of epoxides catalyzed by metal–salen complexes. The research article presents a proline-catalyzed aldol reaction in water–methanol solvent mixture.

Supramolecular Catalysts by Cheng-Yong Su,Leyong Wang Pdf

The construction of catalysts by supramolecular forces has recently become a powerful tool and the role of noncovalent interactions can assist in designing new tools for the construction of effective and selective catalytic systems. It is unquestionably, vastly important to understand how different noncovalent interactions can be controlled or manipulated under appropriate reaction conditions. Supramolecular catalysts have had a tremendous impact on the syntheses of both chemical commodities and fine chemicals over the last 50 years, leading to the discovery of new reactions that were previously deemed impossible. This means that supramolecular chemistry plays a predominant role in accelerating or understanding chemical reactions.This book which addresses the above points is written by some of the leading contributors in this field and is intended for graduate students, researchers and academics working in supramolecular chemistry, organic chemistry, inorganic chemistry, and physical chemistry as well as researchers with an interest in the area of catalysis. The authors give examples illustrating the growth of the field, especially with special emphasis on new results published over the last decade. They also provide an explanation of fundamentals and topical research.
