WebThe selective transformation of 5‐hydroxymethylfurfural (HMF) to valuable 2,5‐diformylfuran (DFF) and 2,5‐dihydroxymethylfuran (DHMF) is highly desirable but remains a great challenge owing to its tendency to over‐oxidation and over‐reduction. In this work, HMF is directly converted into DFF and DHMF without external oxidant or reductant through a … WebSignificant amounts of methyl isobutyl carbinol (MIBC) were also formed by the simultaneous reduction of C C and C O groups of MO.
