Organometallic chemistry nomenclature

The enormous growth in organometallic chemistry over the last fifty years and the discovery of new classes of compounds with unprecedented bonding modes has resulted in the need for additional nomenclature rules for organometallic compounds. This Chapter is therefore considerably expanded over Section 1-10.9 of Ref. 1 and is largely based on the IUPAC recommendations published in 1999 for organometallic compounds of the transition elements.2... 

The second edition of the well-known Red Book, the definitive recommendations of the lUPAC Commission on Nomenclature of Inorganic Chemistry, appeared in Pure Appl. Chem., 28, 1-110 (1971). It is also available separately as a hard-bound reprint. In this edition, the rules for naming organometallic compounds have been completely revised and extended, with introduction of the rj nomenclature for organic ligands.

Neutral substituents on macromolecular chains require no special treatment in terms of constitution or nomenclature to differentiate them from low-molar-mass substances. Practically all the groupings and classifications of low-molar-mass organic, organometallic, and inorganic chemistry can be used with substituents on macromolecular chains. 

Chapter 15 provides a brief introduction to commonly used organic molecules that also have a carbon-metal bond—organometallics. Chapter 16 introduces the fundamental characteristics of molecules that contain the carbon functional group, along with a review of the nomenclature of carbonyl-containing molecules. Carbonyl compounds are often prepared by oxidation reactions, and several key oxidation reactions are discussed in Chapter 17. Oxidation reactions of a few other functional groups are included. Chapter 18 elaborates the chemical reactions of the carbonyl-containing molecules known as aldehydes and ketones. This chemistry is dominated by the acyl addition reaction introduced in Chapter 16. 

In this chapter, we introduce the chemistry of organic compounds that contain transition metals elements. The chemistry of organometallic compounds lies at the interface of inorganic chemistry and organic chemistry. As a prelude to this discussion, we will briefly introduce some basic principles and nomenclature. Then, we will be able to describe the tremendous versatility of organometallic compounds of transition metal elements in organic synthesis. We wfll focus upon a small number of organometaUic reactions and emphasize the basic principles that reach far beyond these reactions.
