Beschreibung

Exploring and highlighting the new horizons in the studies of reaction mechanisms that open joint application of experimental studies and theoretical calculations is the goal of this book.

The latest insights and developments in the mechanistic studies of organometallic reactions and catalytic processes are presented and reviewed. The book adopts a unique approach, exemplifying how to use experiments, spectroscopy measurements, and computational methods to reveal reaction pathways and molecular structures of catalysts, rather than concentrating solely on one discipline. The result is a deeper understanding of the underlying reaction mechanism and correlation between molecular structure and reactivity. The contributions represent a wealth of first-hand information from renowned experts working in these disciplines, covering such topics as activation of small molecules, C-C and C-Heteroatom bonds formation, cross-coupling reactions, carbon dioxide converison, homogeneous and heterogeneous transition metal catalysis and metal-graphene systems. With the knowledge gained, the reader will be able to improve existing reaction protocols and rationally design more efficient catalysts or selective reactions.

An indispensable source of information for synthetic, analytical, and theoretical chemists in academia and industry.

Preface

Understanding electronic structure and reactivity of organometallic compounds remains the problem of fundamental importance in modern chemistry. Development of catalysis and organic chemistry was largely governed by elucidation of reaction mechanisms and utilization of this knowledge to control selectivity and improve yields in synthetic applications dealing with medicinal chemistry, preparation of pharmaceutical and biologically active molecules, industrial processes, fine organic synthesis, new generation of smart materials and organic electronics. In recent decades research in these areas was stimulated by rapid progress in quantum chemistry and utilization of theoretical calculations to reveal correlations between molecular structure, properties, and reactivity.

Theoretical calculations using modern quantum chemical methods provided an outstanding opportunity to make a valuable insight into the problem and allowed reliable description of reaction mechanisms in catalysis from the first principles. Application of informative and flexible computational procedures on numerous examples has demonstrated accurate computational modeling – often within the accuracy achieved in experimental measurements.

Not surprisingly, there is a remarkable interest in modern experimental chemistry to understand computational methods and to apply these methods in the everyday research. In fact, the number of publications that contain both – experiment studies and theoretical calculations – was tremendously increased over the last years. It is not uncommon for purely experimental research groups to learn theoretical methods and facilitate mechanistic studies, especially in the fields where experimental capabilities alone are not sufficient to solve the problem. Rapid increase in the computational power of modern personal computers and easy availability of high performance CPUs even further stimulate this tendency. What is important nowadays, is to transfer the knowledge about state-of-the-art theoretical methods and fascinating opportunities they open in the studies of transition metal chemistry and catalysis.

The role of this book is to highlight new horizons in the studies of reaction mechanisms that open joint application of experimental studies and theoretical calculations. The book is aimed to provide first hand experience from known experts that are practically familiar with such complex studies involving both computational and experimental tools.

The present book chapters review organometallic and catalytic reactions in the gas phase, model systems for studying reactions in solution under homogeneous conditions with soluble metal complexes, as well as complex chemical transformations involving heterogeneous systems. Few chapters are dedicated to describe methodology of computational studies for exploration of catalytic cycles and mechanisms of organometallic reactions.

I would like to express my great thanks to the authors that accepted to contribute to the book for their excellent chapters. Finally, I thank Anne Brennfuehrer and Lesley Belfit from Wiley for continuous help and assistance during development of this book project.

1.1 Introduction

As a consequence of the key positions that the elements carbon and nitrogen occupy in nature, C–N bond formation constitutes an important issue in the synthesis of various products ranging from chemical feedstocks to pharmaceuticals. Not surprisingly, over the last few decades, intensive research has been devoted to this timely topic [1], and the use of ammonia as a relatively inexpensive reagent for C–N coupling reactions has been found to be highly desirable [2]. However, despite the impressive progress reported on the development of new synthetic methodologies, there exists a lack of information on the precise, atomistic-level derived mechanisms in particular for the metal-mediated formation of nitrogen-containing organic molecules generated directly from ammonia. One way to gain such insight is to perform gas-phase experiments on “isolated” reactants. These studies provide an ideal arena for probing experimentally the energetics and kinetics of a chemical reaction in an unperturbed environment at a strictly molecular level without being obscured by difficult-to-control or poorly defined solvation, aggregation, counterion, and other effects. Thus, an opportunity is provided to reveal the intrinsic feature(s) of a catalyst, to explore directly the concept of single-site catalysts, or to probe in detail how mechanisms are affected by factors such as cluster size, different ligands, dimensionality, stoichiometry, oxidation state, degree of coordinative saturation, and charge state. In short, from these experiments, one may learn what determines the outcome of a chemical transformation [3]. In addition, thermochemical and kinetic data derived from these experiments provide a means to benchmark the quality of theoretical studies.

While the study of “naked” gas-phase species will, in principal, never account for the precise kinetic and mechanistic details that prevail at a surface, in an enzyme, or in solution, when complemented by appropriate, computationally derived information, these gas-phase experiments prove meaningful on the ground that they permit a systematic approach to address the above-mentioned questions; moreover, they provide a conceptual framework. The DEGUSSA process, which is the rather unique, platinum-mediated, large-scale coupling of CH and NH to generate HCN [4], serves as a good example. Mass spectrometry-based experiments [5] suggested both the key role of CHNH as a crucial gas-phase transient and also pointed to the advantage of using a bimetallic system rather than a pure platinum-based catalyst for the C–N coupling step to diminish undesired, catalyst-poisoning “soot” formation [6, 7]. The existence of CHNH was later confirmed by photoionization studies [8] and catalysts that are currently employed contain silver-platinum alloys rather than pure platinum.
