Sumario:Mn and Fe BPMEN complexes showed excellent reactivity in catalytic oxidation with an excess of co-reagent (CH(3)COOH). In the straight line of a cleaner catalytic system, volatile acetic acid was replaced by SiO(2) (nano)particles with two different sizes to which pending carboxylic functions were added (SiO(2)@COOH). The SiO(2)@COOH beads were obtained by the functionalization of SiO(2) with pending nitrile functions (SiO(2)@CN) followed by CN hydrolysis. All complexes and silica beads were characterized by NMR, infrared, DLS, TEM, X-ray diffraction. The replacement of CH(3)COOH by SiO(2)@COOH (100 times less on molar ratio) has been evaluated for (ep)oxidation on several substrates (cyclooctene, cyclohexene, cyclohexanol) and discussed in terms of activity and green metrics.
