Abstract
N-Heterocyclic
nitreniums
(NHNs)
are
isoelectronic
and
isostructural
analogues
of
N-heterocyclic
carbenes
(NHCs).
Unlike
NHCs,
NHNs
much
less
developed.
While
a
comprehensive
understanding
NHN
reactivity
remains
elusive,
recent
advancements
have
demonstrated
their
utility
as
Lewis
acid
catalysts,
photoreductants,
photooxidants,
leading
to
several
reaction
patterns.
In
this
short
review,
we
focus
on
the
applications
in
photoredox
reactions.
We
also
discuss
mechanisms
behind
these
transformations
outline
future
research
directions.
