with aldehydes and ketones to provide
trifluoromethylated alcohols. In contrast, the
cathodic reduction of CF 3 Br in the presence of
zinc ions does not provide any desired product
[64]. Hence, anodically generated zinc ions are
very specific and quite different from ordinary
zinc ions.

Other typical examples are the cross-coupling
reaction of activated halogenated compounds
and

carbonyl compounds, and the

cross-coupling reaction between

non-halogenated compounds [65].

5.7 Electrochemical Fluorination

Organofluorine compounds are classified into
two groups: perfluoro compounds and partially
fluorinated compounds. The compounds in the
former class are widely utilized as functional
materials, while those in the latter family find
biological uses as pharmaceuticals and
agrochemicals. Perfluoro compounds are
manufactured by converting all C-H bonds to
C-F bonds using electrochemical fluorination
