Abstract
A
C(

)−H
phosphorylation
has
been
achieved
via
the
iron‐catalyzed
cross‐coupling
reactions
between
1,3‐dicarbonyl
compounds
and
P(O)−H
involving
C−C
bond
cleavages
with
air
as
oxidant.
This
transformation
provides
a
straightforward
way
to
construct
)−P

leading
formation
of
β‐ketophosphine

Phosphorodithioates
are
important
substructures
due
to
their
great
use
in
bioactive
compounds
and
functional
materials.
A
metal-free
1,5-addition
of
spirovinylcyclopropyl
oxindoles
have
been
developed
by
choosing
P4S10
alcohol
as
nucleophiles
through
the
regioselective
ring-opening
oxindoles.
This
method
provides
access
allylic
organothiophosphates
with
high
efficiency,
wide
group
tolerance,
good
chemo-
regioselectivity,
E-selectivity.
1,3-Addition
products
were
also
prepared
yield.
Furthermore,
resulting
could
be
readily
transformed
into
other
derivatives.

A
three-component
reaction
involving
arynes,
trialkyl
phosphites,
and
halides
has
been
achieved
under
mild
conditions.
This
transformation
provides
a
direct
synthetic
approach
to
ortho-halogenated
arylphosphonates,
which
could
be
rapidly
converted
diversely
ortho-functionalized
arylphosphorus
compounds.
