In-Depth Information
applications of such electrochemical reactions
to organic syntheses, limited examples are
given in this chapter. It is recommended that
readers also study other more detailed topics
[1].
5.1 Electrocatalysis
Although indirect electrochemical reactions
using mediators, i.e. electrocatalytic reactions,
have already been explained in
Chapter 2
,
various examples of synthetic applications are
described in this chapter [2]. Some other
synthetic examples are also demonstrated in
Chapters 6
and
7
.
5.1.1 Classification and Kinds of
Mediators
Mediators are classified into two groups, as
shown in
Eqs. 5.1
and
5.2
: outer sphere type
mediators involving electron transfer between
the mediator and a substrate molecule (
Eq. 5.1
),
and inner sphere type mediators involving
redox reaction through ordinary chemical
reactions (
Eq. 5.2
), as shown in
Table 5.1
.
