Additive nomenclature organometallics

Thus organometallic compounds can be named by an additive or a substitutive process. Additive nomenclature is applicable to all organometallic compounds, but substitutive nomenclature is arbitrarily restricted to names of derivatives of specific metals, the elements of Groups 14, 15, 16 and 17, and boron.

Additive nomenclature treats a compound or species as a combination of a central atom or central atoms with associated ligands. The particular additive system used for coordination compounds (see Chapter IR-9) is sometimes known as coordination nomenclature although it may be used for much wider classes of compounds, as demonstrated for inorganic acids (Chapter IR-8) and organometallic compounds (Chapter IR-10) and for a large number of simple molecules and ions named in Table IX. Another additive system is well suited for naming chains and rings (Section IR-7.4 see Example 6 below). 

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... 

When an organometallic compound contains two or more different metal atoms, a choice must be made to provide the basis of the name. It is thus convenient to classify the possible central atoms as belonging to either (i) the elements of groups 1-12 (whose compounds are named according to the additive system of nomenclature) or (ii) the elements of groups 13-16 (whose compounds are named according to the substitutive system). 

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.
