Скачать книгу - Catalytic Asymmetric Conjugate Reactions



This unique and long-awaited handbook on this important topic in the hot field of stereoselective organic synthesis covers several types of nucleophiles. Top international authors deal with modern forms of achieving stereoselective conjugate additions based on the use of chiral auxiliaries or asymmetric catalysis, such as P-N ligands, organocatalysis, domino reactions, Lewis acid and base catalysis. There is also a discussion of the employment of enantioselective conjugate addition transformations in total synthesis of important molecules. With its reliable and previously unpublished experimental procedures, this is a true source of high quality information.


Influence of asymmetrical military confrontation on market structure. From the Behavioral point of view by Semiotic approach Influence of asymmetrical military confrontation on market structure. From the Behavioral point of view by Semiotic approach

Автор: Georgi Hristov

Год издания: 

In this work I look how the conflicts influence on the market structure and its peculiar communication. At the same time is appraised the semiotic substance and power of the signs for the interpretation of a coercive changing economic reality. In the specific aspects of examination are included typical moments of military confrontation in Ukraine and in the territories, where Islamic State has activity. Some observations of the wars in ex-Yugoslavia from the 90s are also included.

Palladium-Catalyzed Coupling Reactions. Practical Aspects and Future Developments Palladium-Catalyzed Coupling Reactions. Practical Aspects and Future Developments

Автор: Molnar Arpad

Год издания: 

This handbook and ready reference brings together all significant issues of practical importance in selected topics discussing recent significant achievements for interested readers in one single volume. While covering homogeneous and heterogeneous catalysis, the text is unique in focusing on such important aspects as using different reaction media, microwave techniques or catalyst recycling. It also provides a comprehensive treatment of key issues of modern-day coupling reactions having emerged and matured in recent years and emphasizes those topics that show potential for future development, such as continuous flow systems, water as a reaction medium, and catalyst immobilization, among others. With its inclusion of large-scale applications in the pharmaceutical industry, this will equally be of great interest to industrial chemists.

Modeling and Simulation of Catalytic Reactors for Petroleum Refining Modeling and Simulation of Catalytic Reactors for Petroleum Refining

Автор: Jorge Ancheyta

Год издания: 

Modeling and Simulation of Catalytic Reactors for Petroleum Refining deals with fundamental descriptions of the main conversion processes employed in the petroleum refining industry: catalytic hydrotreating, catalytic reforming, and fluid catalytic cracking. Common approaches for modeling of catalytic reactors for steady-state and dynamic simulations are also described and analyzed. Aspects such as thermodynamics, reaction kinetics, process variables, process scheme, and reactor design are discussed in detail from both research and commercial points of view. Results of simulation with the developed models are compared with those determined at pilot plant scale as well as commercial practice. Kinetics data used in the reactor model are either taken from the literature or obtained under controlled experiments at the laboratory.


Organic Mechanisms. Reactions, Methodology, and Biological Applications Organic Mechanisms. Reactions, Methodology, and Biological Applications

Автор: Xiaoping Sun

Год издания: 

Instills a deeper understanding of how and why organic reactions happen Integrating reaction mechanisms, synthetic methodology, and biological applications, Organic Mechanisms gives organic chemists the tools needed to perform seamless organic reactions. By explaining the underlying mechanisms of organic reactions, author Xiaoping Sun makes it possible for readers to gain a deeper understanding of not only chemical phenomena, but also the ability to develop new synthetic methods. Moreover, by emphasizing biological applications, this book enables readers to master both advanced organic chemistry theory and practice. Organic Mechanisms consists of ten chapters, beginning with a review of fundamental physicochemical principles that are essential for understanding the nature of organic mechanisms. Each one of the remaining chapters is devoted to a major class of organic reactions, including: Aliphatic C–H bond functionalization Functionalization of the alkene C=C bond by cycloaddition reactions Nucleophilic substitutions on sp3-hybridized carbons Nucleophilic additions and substitutions on carbonyl groups Reactivity of the ?-hydrogen to carbonyl groups Rearrangements A brief review of basic organic chemistry begins each chapter, helping readers move from fundamental concepts to an advanced understanding of reaction mechanisms. Key mechanisms are illustrated by expertly drawn figures highlighting microscopic details. End-of-chapter problems enable readers to put their newfound knowledge into practice by solving key problems in organic reactions with the use of mechanistic studies, and a Solutions Manual is available online for course instructors. Thoroughly referenced and current with recent findings in organic reaction mechanisms, Organic Mechanisms is recommended for upper-level undergraduates and graduate students in advanced organic chemistry, as well as for practicing chemists who want to further explore the mechanistic aspects of organic reactions.
