Table 2 reports comparisons between the proposed modification of the Pitzer method and the Tsonopoulos method for alkyl halides
, mercaptans, sulphides, disulphides and ethers representing the class of slightly polar compounds.
Ferrocene is known to readily form charge transfer complexes (CTCs) with alkyl halides
, as evidenced by the appearance of a feature indicative of a charge transfer complex at ~310 nm; subsequently, upon irradiation, the complex dissociates into the ferrocenium ion, chloride ion, and alkyl radical (Fig.
The only notable omission is that there is no treatment of alkyl halides
as ligands, even though many complexes are known in which C-X groups are bonded to metal ions (especially when X = F).
