Styrene epoxidation over heterogeneous manganese(III) complexes

The manganes(III) complex functionalised with 2,3-dihydropyridazine has been encapsulated in the supercages of the NaY zeolite using two different procedures, flexible ligand and in situ complex. The parent zeolite and the encapsulated manganese(III) complexes were screened as catalysts for styrene oxidation by using t-BOOH as the oxygen source in acetonitrile. Under the optimized conditions, the catalysts exhibited moderate activity with high selectivity to benzaldehydeIKB thanks to Foundation for the Science and Technology (FCT, Portugal), for the contract under 'Programa Ciencia 2007 and for the contract under the project "n-STeP - Nanostructured systems for Tail" (NORTE-07-0124-FEDER-000039, supported by Norte (ON.2).
