Introduction to the Chemistry of Transition Metals

The reactions in this chapter are organized according to the overall transformation achieved. An organization by mechanistic type (insertions, transmetallations, etc.) was considered and rejected. The purpose of this text is to teach the student how to go about drawing a mechanism for an unfamiliar reaction. A student who does not already know the mechanism for a reaction will find it easier to narrow down the possible mechanisms by considering the overall transformation rather than by trying to determine the mechanistic type. An organization by metal (early, middle, or late) was also considered and rejected, because it would obscure the important similarities between the reactions of different metals.

The choice of topics is largely governed by the author s interests. Following a brief introduction the crystal field model is described non-mathematically in chapter 2. This treatment is extended to chapter 3, which outlines the theory of crystal field spectra of transition elements. Chapter 4 describes the information that can be obtained from measurements of absorption spectra of minerals, and chapter 5 describes the electronic spectra of suites of common, rock-forming silicates. The crystal chemistry of transition metal compounds and minerals is reviewed in chapter 6, while chapter 7 discusses thermodynamic properties of minerals using data derived from the spectra in chapter 5. Applications of crystal field theory to the distribution of transition elements in the crust are described in chapter 8, and properties of the mantle are considered in chapter 9. The final chapter is devoted to a brief outline of the molecular orbital theory, which is used to interpret some aspects of the sulphide mineralogy of transition elements. 

Chapter 12 serves as an introduction to a huge area of chemistry devoted to the use of organometallic compounds for the construction of complex molecules. The material covered in Chapter 12 exemplifies several of the most important applications of organotransition metal chemistry to organic synthesis. Thousands of articles have appeared over the past 10 years that report on either the use of transition metal compounds in key steps of syntheses, which would be difficult or even impossible to carry out without transition metals, or on the development of novel methodology that may have many applications to synthesis down the road. Research on the connection between organometallic chemistry and synthesis remains active and fruitful, and there is every indication that this endeavor will continue to hold the interest of chemists for many years to come.

ADMET is quite possibly the most flexible transition-metal-catalyzed polymerization route known to date. With the introduction of new, functionality-tolerant robust catalysts, the primary limitation of this chemistry involves the synthesis and cost of the diene monomer that is used. ADMET gives the chemist a powerful tool for the synthesis of polymers not easily accessible via other means, and in this chapter, we designate the key elements of ADMET. We detail the synthetic techniques required to perform this reaction and discuss the wide range of properties observed from the variety of polymers that can be synthesized. For example, branched and functionalized polymers produced by this route provide excellent models (after quantitative hydrogenation) for the study of many large-volume commercial copolymers, and the synthesis of reactive carbosilane polymers provides a flexible route to solvent-resistant elastomers with variable properties. Telechelic oligomers can also be made which offer an excellent means for polymer modification or incorporation into block copolymers. All of these examples illustrate the versatility of ADMET. 

This volume, which is unique in its coverage, provides a general introduction to the properties and nature of transition metal carbides and nitrides, and covers their latest applications in a wide variety of fields. It is directed at both experts and nonexperts in the fields of materials science, solid-state chemistry, physics, ceramics engineering and catalysis. The first chapter provides an overview, with other chapters covering theory of bonding, structure and composition, catalytic properties, physical properties, new methods of preparation, and spectroscopy and microscopy.
