Epoxidation of alkenes by a readily prepared and highly active and reusable heterogeneous molybdenum-based catalyst Original Research Article

Polymer-bound piperazine was readily prepared from Merrifield resin and was used as a robust support for immobilization of molybdenum hexacarbonyl. This polymer-supported molybdenum catalyst shows high activity in the epoxidation of various alkenes in the presence of tert-butylhydroperoxide (TBHP). This new heterogenized molybdenum catalyst can be recovered and reused for eight times without loss of its activity.
