α-Fluoro-α′-aryl
ketones
are
crucial
in
pharmaceuticals
and
agrochemicals.
However,
synthesizing
unsymmetrical
α-fluoro-α′-aryl
poses
regioselective
challenges.
This
study
presents
a
one-pot
aryl-oxy-fluorination
method
for
such
fluoro-aryl
ketones.
Using
ynamide,
aryl
boronic
acid,
F-source
under
Pd-catalysis,
this
efficiently
produces
wide
range
of
valuable
with
potential
applications.
Through

Presently,

an
approach
to
yield
tetrasubstituted
