Epoxidation Of Cyclohexene

In the present work, the highly efficient epoxidation of cyclohexene catalyzed by Fe3O4@SiO2/([Mn2L(HL)(H2O)4], is reported. First, the Fe3O4@SiO2 nanoparticles were modified with (3-chloropropyl)-trimethoxysilane (CPTMS) group and then [Mn2(HL)2(H2O)4] was attached to the support via covalent linkages. The prepared catalyst was characterized by spectroscopic studies and chemical analyses. This catalytic system serves as catalyst for the oxidation of cyclohexene to cyclohexene epoxide and 2-cyclohexene-1-ol using H2O2 as an oxidant. Thus, this catalytic system shows high activity and selectivity toward cyclohexene epoxide. Also activity of the immobilized catalyst remains nearly unchanged after five cycles, that it is truly heterogeneous.
