Abstract: Two new mononuclear Schiff base complexes, [MLCl(H2O)2] [M = Mn(III) or Fe(III); H2L = 2-phenoliminomethylphenol], have been prepared and characterized by elemental analysis, thermogravimetric analysis, UV-vis and FT-IR spectroscopy, cyclic voltammetry and ESI-MS analyses. Both complexes show excellent alkenes epoxidation activity and thus these complexes have been infused over neutral active alumina to prepare the heterogeneous catalysts. These catalysts are characterized by solid UV-vis and FT-IR spectroscopy, thermogravimetric and powder XRD and FE-SEM studies. Finally, the catalysts have been studied for the epoxidation of different types of olefins in presence of terminal oxidants (PhIO and t-BHP) and are easily recyclable.
