Preparation of encapsulated and anchored alanine-salicylaldehyde Schiff base Mn(III) (Sal-Ala-Mn) complexes by sol-gel method and their performance in aerobic epoxidation of cyclohexene

Two heterogenized catalysts entrapping alanine-salicylaldehyde Shiff base Mn(III) complex were prepared. They were characterized by FT-IR, XPS, N2 adsorption and ICP and their catalytic performance for the aerobic epoxidation of cyclohexene were investigated.
