Epoxidation of alkenes by a readily prepared and highly active and reusable heterogeneous molybdenum-based catalyst
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 tertbutylhydroperoxide (TBHP). This new heterogenized molybdenum catalyst can be recovered and reused for eight times without loss of its activity. (c) 2005 Elsevier B.V. All rights reserved.
