Biomass as a sustainable and abundant carbon source has attracted considerable attention as a potential alternative to petroleum resources. The selective oxidation of 5-hydroxymethylfurfural (HMF), a versatile platform molecule, to value-added 2,5-diformylfuran (DFF) provides an efficient pathway for biomass valorization. Herein, three discrete imidazole-functionalized polyoxometalates (POMs), HPMo 8have been successfully synthesized by a facile solvothermal method and thoroughly characterized by routine techniques. Compounds 1−3 contain a bi-capped pseudo-Keggin {HPMo 8 V 4 O 40 (VO) 2 } and two imidazole-functionalized {(VO)(IM) 4 } groups, which, to our knowledge, represent the first examples of organic-functionalized Mo−V clusters. Compounds 1−3 as heterogeneous catalysts can effectively promote the transformation of HMF to DFF using atmospheric O 2 as oxidant.Under minimally optimized conditions, 95% of HMF was converted by 1 with 95% selectivity for DFF and its catalytic activity was basically maintained after five cycles. Moreover, the important roles of the bi-capped pseudo-Keggin cluster and the functionalized V groups in the selective oxidation of HMF have been explored. According to experimental and spectroscopic results, a three-step oxidation mechanism of HMF to DFF has been proposed.
