Preparation and catalytic properties of polymer-bound Schiff base ternary complexes

The polymer-bound Schiff base ternary cobalt complexes (PS-SalPhe-Co-L (L = Phen, Bipy and 8HQ)) have been prepared from the polymer bound Schiff base ligand, cobalt salt and the second ligand, such as 1,10-phenanthroline(phen), 2,2',-bipyridyl(bipy) and 8-quinolinol(8HQ). The polymer-bound Schiff base ternary cobalt complexes were characterized by the infrared spectra and ICP-AES. The catalytic activity of the complexes has been studied in aerobic epoxidation of long-chain linear aliphatic olefins. It showed that 1-octene or 1-decene can be directly oxidized by molecular oxygen catalyzed by PS-SalPhe-Co-L (L = Phen, Bipy and 8HQ), which afford the 1,2-epoxy alkane.
