Abstract
Low‐valent
chromium
catalysts

cheap
and
less
toxic
compared
to
other
transition
metal
catalysts.
Here
in,
we
reported
a
ligand‐free
chromium(III)‐catalyzed
manganese
reductive
cross‐coupling
of
unactivated
alkyl
electrophiles,
such
as
sulfonates
chlorides,
with
trisulfide
dioxides
thiolation
agents

carbon−sulfur
bonds.
The
powerful
method
featured
ample
