Hybrid polyoxotungstates as functional co-monomers in new cross-linked catalytic polymers for sustainable oxidations with hydrogen peroxide

The hybrid organic inorganic polyoxometalates [(CH2=CH(CH2)6Si)xOySiWwOz]4-, with x=2, w=11, y=1, z=39 (1); x=2, w=10, y=1, z=36 (2) and x=4, w=9, y=3, z=34 (3) have been synthesized and co-polymerized with methyl methacrylate, to obtain porous materials with homogeneous catalyst distribution. Their reactivity towards the activation of hydrogen peroxide in acetonitrile has been screened, using methyl p-tolyl sulfide as a model substrates. The hybrid material containing the bivacant polyanion (2) was also employed in octane, to evaluate the oxidation and removal of a well-known gasoline contaminant, dibenzothiophen
