Abstract
A
molybdenum‐catalyzed
synthesis
of
N
‐(hetero)aryl
pyrroles
directly
from
inexpensive
and
commonly
available
(hetero)nitroarenes
via
reduction
with
pinacol

1,4‐dicarbonyls
or
cyclobutane‐1,2‐diols
has
been
described.
The
process
does
not

This
non‐noble
catalytic
system
shows
high
chemoselectivity,
allowing
a
diverse
range

such
as
alkynes,
alkenes,

Moreover,
this
strategy
enables
