Diformylfurane (DFF) has been obtained by aerobic oxidation of 5-hydroxymethyl-2-furaldehyde (HMF) with homogeneous pyridine-vanadyl complexes in homogeneous phase, with Cu and V in poly(4-vinylpyridine) crosslinked with 33% divinylbenzene (PVP) and supported on organofunctionalized SBA-15 mesoporous materials. Detailed spectroscopic characterization of the materials is provided. Catalytic results show that pyridinevanadyl complexes supported on SBA-15 are less active than when in the polymeric form. The nature of the catalyst surface and solvent plays a key role on the catalytic behaviour.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
