Replacement of Volatile Acetic Acid by Solid SiO(2)@COOH Silica (Nano)Beads for (Ep)Oxidation Using Mn and Fe Complexes Containing BPMEN Ligand

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 a...

description 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.
