Polymer-supported bis (2- hydroxylanyl) acetylacetone Schiff base ligand was prepared by reaction of bis (2- hydroxylanyl) acetylacetone with chloromethylated polystyrene in DMF. In the subsequent reaction of this polymer-supported Schiff base ligand with MoO2(acac)2 the polymer-supported bis (2- hydroxylanyl) acetylacetonato MoO2 Schiff base complex was prepared. This polymer-supported molybdenum Schiff base catalyst was highly active and selective in epoxidation of various alkenes in the presence of tert-buthyl hydroperoxide (TBHP) in CCl4. It can be recovered and reused for 8 times without any loss in its activity.
