Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...
