Organic ligands abbreviations

The optically active organic ligands used in this chapter are broad ranging [6]. Some ligands 1-17 are listed in Figure 2.1, but for other abbreviated ligands the full names are described in the appropriate references. 

An abbreviation for an organic ligand should be derived from a name consistent with the current rules for the systematic nomenclature of organic compounds.4 (For some ligands a non-systematic name is included in Table VII if it was the source of the abbreviation and if that abbreviation is still commonly used.) New abbreviations should further be constructed according to the following recommendations ... 

Abbreviations can be used to represent complicated organic ligands in formulae (although they should not normally be used in names). When used in formulae they are usually enclosed in parentheses. 

Abbreviations of names for organic ligands appear sometimes in formulae. Following the recommendations by lUPAC, lower case letters are used, and if necessary, the ligand abbreviation is enclosed within parentheses. Flydrogen atoms that can be replaced by the metal atom are shown in the abbreviation with an upper case H , for example Hjedta, Am(Hedta)(s) (where edta stands for ethylenediaminetetraacetate). 

In order to save space many of the organic ligands will be designated by commonly used abbreviations such as the following ... 

H+ and e are transferred from one donor to one acceptor in a single kinetic step (eqn (1.1)). The definitions and abbreviations of the organic ligands used in the transition metal HAT systems deseribed below are given in ref. 54. 

The common abbreviations are used M = metal, L = ligand, R = organic group, Me = methyl, Et = ethyl, Pr = propyl, Bu = butyl, Ar = aromatic group. Ph = phenyl, Cp = cyclopentadienyl, Hal = halogen, X = anionic substituent. Short straight lines around metal atoms denote carbonyl hgands omitted for the sake of clarity.
