Triphenylphosphine phenylimide
Triphenylphosphine
phenylimide
is the
organophosphorus compound
with the
formula
Ph
3
P=NPh. It is a
white
solid
that is
soluble
in
organic solvents
.
The compound
is a
prototype
of a large
class
of
Staudinger
reagents
, resulting from the
Staudinger reaction
.
The
phosphine
imides were first prepared in the
laboratory
of
Nobelist
Hermann Staudinger
. His
synthesis
involved the
direct
reaction
of
triphenylphosphine
with
phenylazide
.
X-ray crystallography
establishes
that the P-N-C
angle
is
bent
and the P-N distance is 160 pm.
