6.2 Electrolytic Systems Using
Solid Bases and Acids
Ordinary soluble bases are readily oxidized
anodically, but insoluble solid-supported bases
are not oxidized at the anode. Based on this
fact, new electrolytic systems have recently
been developed using recyclable and reusable
solid-supported bases and acids as supporting
electrolytes [5-8]. For instance, as shown in
Figure 6.4
, solid (silica gel or porous
polystyrene)-supported bases like piperidine
dissociate protic organic solvents like methanol
and acetic acid to protons and anions, and the
resulting protons act as the main carriers of
electronic charge.

Dissociation of protic solvents by
solid base
This system is widely applicable to various
anodic nucleophilic substitutions, such as
methoxylation and acetoxylation of various
compounds (
Eq. 6.1
). Moreover, it is notable
that after the electrolysis, solid-supported bases
