The polymer bound Schiff-base ligand (PS-SalGlu) has
been prepared from polystyrene bound salicylaldehyde
and glutamic acid, and its complex (PS-SalGlu-Co) has
also been synthesized. The polymer ligand and its
complex were characterized by infrared spectroscopy,
small area X-ray photoelectron spectroscopy, and
inductively coupled plasma-atomic emission spectro
(ICP-AFS). In the presence of the complex, cyclohexene
can be effectively oxidized by molecular oxygen without
reductant. The long-chain linear aliphatic olefins, such as
1-octene, 1-decene, 1-dodecene and 1-tetradecene, can be
directly oxidized by molecular oxygen catalyzed by PS-
SalGlu-Co, which affords the 1,2-epoxy alkane.
