Abstract
Selective
functionalization
via
cleavage
of
the
C–N
bond
amines
has
proven
to
be
challenging
partly
because
its
relatively
high
dissociation
energy,
even
though
are
abundant
and
readily
available.
To
meet
this
challenge,
many
new
transformations
based
on
pre-activation
before
have
been
developed.
Among
them,
conversion
into
quaternary
ammonium
salts
certain
advantages,
such
as
easy
preparation
from
primary,
secondary,
or
tertiary
amines,
well
stable
storage
usage.
Although
transition
metal
catalysis
frequently
applied
for
developing
oxidative
addition
salts,
recent
studies
shown
a
dimension
by
using
green
electro-
photochemical
tools.
In
short
review,
advances
in
electro-,
photo-,
photoelectrochemical
driven
synthetic
applications
summarized
discussed.

The
first
paired
electrolysis-enabled
arylation
of
quinoxalin-2(1H)-ones
was
achieved
using
cyanoarenes
as
the
reagents.
A
variety
3-arylquinoxalin-2(1H)-ones
with
various
important
functional
groups
were
obtained
in
moderate
to
good
yields
under
metal-
and
chemical
oxidant-free
conditions.
With
a
pair
reductive
oxidative
processes
occurring
among
substrates
reaction
intermediates,
power
consumption
can
be
dramatically
reduced.

from
easily

reported.
Using

of

be
efficiently
