•A new porous copolymer-anchored Molybdenum acetylacetonate oxygen catalyst is prepared.•The catalyst leads to the heterogeneous epoxidation of alkenes with tert-butyl hydroperoxide.•The catalyst presents relative high conversion and selectivity.•The catalyst could be easily recovered and reused.
This work describes the immobilization of molybdenum acetylacetonate oxygen (MoO2(acac)2) on cross-linked porous copolymer support via covalent attachment under mild conditions. The obtained solid product DVB–AA–Mo was fully characterized by FT-IR, TG, CHN elemental analysis, nitrogen adsorption/desorption, and SEM, and was tested for the epoxidation of various alkenes with tert-butyl hydroperoxide (TBHP) as the oxidant. DVB–AA–Mo was proved to be a highly efficient catalyst for epoxidation reactions, it could easily be recovered by filtration and reused for five runs without significant loss in activity.
