New Directions in the Modeling of Organometallic Reactions


Book Description

This book focuses on the computational modeling of organometallic reactivity. In recent years, computational methods, particularly those based on Density Functional Theory (DFT) have been fully incorporated into the toolbox of organometallic chemists’ methods. Nowadays, energy profiles of multistep processes are routinely calculated, and detailed mechanistic pictures of the reactions arise from these calculations. This type of analysis is increasingly performed even by experimentalists themselves. The volume aims to connect established computational organometallics with the more recent theoretical and methodological developments applied to this field. This would allow broadening of the simulation scope toward emergent organometallic areas (as ligand design or photoactivated processes), to narrow the gap between calculations and experiments (microkinetic models) and even to discover new reactions (automated methods). Given the broad interest and extensive application that computational methods have reached within the organometallic community, this new volume will attract the interest of both experimental and computational organometallic chemists.




Supramolecular Catalysis


Book Description

Supramolecular Catalysis Provides a timely and detailed overview of the expanding field of supramolecular catalysis The subdiscpline of supramolecular catalysis has expanded in recent years, benefiting from the development of homogeneous catalysis and supramolecular chemistry. Supramolecular catalysis allows chemists to design custom-tailored metal and organic catalysts by devising non-covalent interactions between the various components of the reaction. Edited by two world-renowned researchers, Supramolecular Catalysis: New Directions and Developments summarizes the most significant developments in the dynamic, interdisciplinary field. Contributions from an international panel of more than forty experts address a broad range of topics covering both organic and metal catalysts, including emergent catalysis by self-replicating molecules, switchable catalysis using allosteric effects, supramolecular helical catalysts, and transition metal catalysis in confined spaces. This authoritative and up-to-date volume: Covers ligand-ligand interactions, assembled multi-component catalysts, ligand-substrate interactions, and supramolecular organocatalysis and non-classical interactions Presents recent work on supramolecular catalysis in water, supramolecular allosteric catalysis, and catalysis promoted by discrete cages, capsules, and other confined environments Highlights current research trends and discusses the future of supramolecular catalysis Includes full references and numerous figures, tables, and color illustrations Supramolecular Catalysis: New Directions and Developments is essential reading for catalytic chemists, complex chemists, biochemists, polymer chemists, spectroscopists, and chemists working with organometallics.

Chirogenesis In Chemical Science


Book Description

Chirogenesis in Chemical Science is an exciting new book that takes readers inside the world of chirality and chirogenesis, guided by Victor Borovkov and Riina Aav, both internationally renowned experts on chirality. Chirality is a fundamental property of the universe and has significance in different organic/inorganic materials, living organisms, and human beings. The basic principle of chirality is existence of an object in two mirror image forms, which are not superimposable. This phenomenon is widely seen in various fields of knowledge including mathematics, astronomy, physics, chemistry, biology and ranging in scale from galaxies to nuclear particles.In chemical science, chirality is generally associated with a single molecule or group of molecules, which symmetry properties belonging to the Cn or Dn point groups with the simplest example of sp3 carbon atom bonded to four different substituents. The dynamic processes of chirality generation, modulation, transfer, amplification, etc. are termed chirogenesis.This is a fast-growing and interdisciplinary field of research, which is widely seen in many natural systems (such as DNA double helix, the secondary alpha-helix structure of proteins, lipid membranes, saccharides, heme proteins, and other biological molecular objects) and various artificial systems. It is of prime importance not only for fundamental science but also for a number of practical applications in such areas as pharmacology and agrochemistry, perfumery and food industry, materials and polymer sciences, enantioselective catalysis and nonlinear optics, nanoscience and nanotechnology, molecular devices and chemical sensors, and others. Therefore, understanding the mechanisms and various influencing factors is of particular significance for smart control and further effective application of chirogenesis in chemistry.

Organometallic Modeling of the Hydrodesulfurization and Hydrodenitrogenation Reactions


Book Description

The fields of hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) continue to attract the attention of researchers in the various disciplines connected to these fascinating problems that represent two of the key outstanding chemical challenges for the petroleum refining industry in view of their very strong environmental and commercial implications. One area that has flourished impressively over the last 15 years is the organometallic chemistry of thiophenes and other related sulfur-containing molecules. This has become a powerful method for modeling numerous surface species and reactions implicated in HDS schemes, and nowadays it represents an attractive complement to the standard procedures of surface chemistry and heterogeneous catalysis, for understanding the complex reaction mechanisms involved in this process. Similar developments have begun to appear in connection with HDN mechanisms, although in a much more modest scale and depth. Some years ago when, encouraged by Prof. B. R. James, this book was planned, several excellent reviews and monographs treating different aspects of HDS were already available including some on the subject of organometallic models. However, it seemed appropriate to try to summarize the most striking features of this chemistry in an updated and systematic way, and inasmuch as possible in connection with the common knowledge and beliefs of the mechanisms of heterogeneous HDS catalysis. Hopefully, this attempt to build some conceptual bridges between these two traditionally separated areas of chemistry has met with some success.
