bromide ions enables the oxidation of alcohols
at much lower oxidation potential [9].

5.1.2.5 Electrosynthesis Using Hypervalent
Compounds as Mediators
Anodic oxidation of p -methoxyiodobenzene in
the presence of fluoride ions provides the
corresponding hypervalent difluoroiodo
derivative, which is a useful fluorinating
reagent. Thus, p -methoxyiodobenzene has been
demonstrated to be a highly efficient mediator
for anodic fluorodesulfurization of dithioacetals
as shown in Figure 5.3 [10]. This is the first
successful example of the catalytic use of
hypervalent compounds for organic synthesis as
well as organic electrosynthesis.
