Synthesis, Characterization and Studies on Catalytic Behavior of Mn(II) Complex with 2, 2' Bipyridine, 1, 1' Dioxide Ligand within Nanoreactors of MCM-41.

Manganese (ii) complex with 2, 2' bipyridine, 1, 1' dioxide (bpdo) ligand was immobilized within nanoreactors of mcm-41. the immobilized complex was characterized by powder x-ray diffraction (xrd), nitrogen adsorption desorption, and ftir. the pore volume, surface area and pore diameter of mcm-41 decreased after immobilization of mn complex. three bands observed at 1250, 1220 cm^-1 and 757 cm^-1 are attributed to the no stretching and bending vibrations respectively. it was found that the immobilized mn complex on mcm-41 successfully catalyzed the oxidation of cyclohexene, styrene, norbornene, and trans-stilbene with tert-butylhydroperoxide (tbhp).with the exception of cyclo-hexene, the other three olefins afforded the corresponding epoxides efficiently. preparation and catalytic effect of mn salt either on mcm-41 or modified mcm-41 with aminopropyltriethoxysilane; mcm-41(ap) will be discussed.
