The enhanced catalytic activity and stability of oxodiperoxomolybdenum-modified mesoporous organosilicas in selective epoxidation reactions

Complexes of the type (L-L) MoO(O-2)(2) heterogenized on phenylene-bridged mesoporous organosilicas show a 10-fold increase in catalytic activity and a high stability in liquid phase epoxidation reactions, with H2O2 as the oxidant, compared to the corresponding MCM-41-derived systems.
