| Description |
The first successful synthesis of poly(ethylene
glycol) (PEG) immobilized iron(II) porphyrin
using a copper-catalyzed azide-alkyne [3+2] cycloaddition
is reported. In contrast to the existing methods
for the synthesis of PEG-immobilized metalloporphyrins,
the click method offers better catalyst loading
under comparatively mild reaction conditions.
The prepared complex 5 (PEG-C51H39FeN7O) was
found to be an efficient catalyst for the selective olefination
of aldehydes with ethyl diazoacetate in the
presence of triphenylphosphine and afforded excellent
olefin yields with high (E) selectivities. The
PEG-supported catalyst 5 was readily recovered by
precipitation and filtration and was recycled for up
to ten runs without significant loss of activity.
