Methods
for
aryne
difunctionalization
have
been
the
focus
of
recent
research,
but
one
limitation
is
use
nucleophiles
with
proton
sources.
Herein,
we
demonstrate
halogen

reagents
to
enable
protic
amines
in
aminohalogenation
difunctionalizations
up
86%

This
method
uses

Through
derivatizations,
synthetic
