Abstract
A
general
protocol
for
the
photorearrangement
of
substituted
benzo‐
and
naphthoquinones
using
monochromatic
blue
light
irradiation
in
solution
was
developed.
During
this
process,
quinone
ring
is
transformed
into
hydroquinone,
while
substituent
undergoes
desaturation
or
annulation
onto
proximal
oxygen
formed
hydroquinone.
We
found
that
preferred
acyclic
saturated
substituents,
such
as
alkyl
groups,
tendency
observed
both
cyclic
unsaturated
substituents
(allyl,
alkenyl,
aryl).
The
diversity
participating
functional
group
tolerance
transformation
allowed
us
to
prepare
10
natural
phenolic
compounds,
suggesting
visible
may
likewise
induce
their
formation
from
respective

sources.
Ruthenium
complex
Ru(p-cymene)@Aza-COF
was
synthesized
by
the
immobilization
of
[Ru(p-cymene)Cl][Cl]
on
a
2D
Aza-COF.
Then,
this
utilized
as
an
auto-tandem
catalyst
for
preparation
quinazolinones
from
allylic
alcohols
and
o-aminobenzamides
via
redox
isomerization/acceptorless
dehydrogenative
coupling.
More
importantly,
its
catalytic
activity
is
well
maintained
during
six
runs.
