In this chapter, the general features of
electrolytic reactions and differences between
electrolytic reactions and ordinary chemical
ones will be explained. Typical characteristics
such as umpolung (polarity inversion) and
selectivity control together with electron
transfer control are discussed. Reaction types
and various electrochemically generated
reactive species will also be explained [1-6].
4.1 General Characteristics of
Electrode Reactions
Organic electrode reactions have the following
features, many of which cannot be achieved by
other methods:
Electrode reactions are typically
heterogeneous reactions, and the reaction
fields are specific since oxidation and
reduction take place separately at different
fields.
Umpolung (polarity inversion) is readily
performed without the use of any reagents.
The selectivity of electrode reactions is often
different from that of ordinary organic
reactions.
