Sustainable Catalytic Synthesis of 2,5-Diformylfuran from Various Carbohydrates

Versatile homogeneous and heterogeneous catalysts that convert carbohydrates to 2,5-diformylfuran (DFF) are essential for the development of sustainable processes producing high-value chemicals from biomass-derived carbohydrates. An efficient catalytic system consisting Br−, disulfide, dimethylsulfoxide (DMSO) promoted selective synthesis DFF in modest-to-good yields various carbohydrates, such as fructose, glucose, mannose, galactose, sucrose. Heterogeneous containing Br− also facilitated this reaction with recyclable high yields.
