Hybrid compounds of Schiff base Cu, Fe, Co complexes with molybdovanadophoric heteropolyacids: synthesis, characterization and their catalytic performance to hydroxylation of benzene with H2O2

A series of transition metal alanine-salicylaldehyde Schiff base chromium (III) complexes immobilized on MCM-41 were prepared and characterized by various physico-chemical measurements such as FIIR, XRD, HRTEM, N2 sorption and elemental analysis. The immobilized complexes were effective and stable catalysts for the epoxidation of styrene and cyclohexene with 30% hydrogen peroxide. Moreover, the metal centers were found to play important roles in the catalytic performance of immobilized complex catalysts.

Immobilization of metal complexes on solid supports is an efficient approach to circumvent the drawbacks of homogeneous catalysis. In this paper, using graphene oxide as carrier, manganese Schiff base supported on graphene oxide (Salen Mn-GO) was prepared through aminosilane covalent modification as well as salicylaldehyde condensation and coordination reaction. The structures and properties of the composite were examined by FT-IR, XRD, XPS, TEM, TG techniques, and the catalytic performance of Salen Mn-GO in styrene epoxidation was explored. The effects of catalyst and styrene amount as well as that of reaction time on the performance of the catalyst were investigated. The results showed that Salen Mn-GO has excellent catalytic activity and reusability for epoxidation of styrene in the presence of hydrogen peroxide. Finally, the mechanism of styrene epoxidation catalyzed by Salen Mn-GO has been preliminarily discussed.
