“…The depletion of fossil resources together with their contribution to environmental issues related to CO 2 emissions have stimulated research towards the synthesis of chemicals from renewable resources, such as lignocellulosic biomasses [1]. In this regard, 5-hydroxymethylfurfural (HMF) is a key platform-chemical, accessible from monosaccharides and polysaccharides [2][3][4][5][6][7][8][9], and the precursor for several value-added products, such as 2,5furandicarboxylic acid (FDCA), 2,5-dimethylfuran (DMF), 2,5-bis (hydroxymethyl)furan (BHMF), and 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF) [9][10][11][12][13][14][15][16][17][18].The two last compounds are obtained from the hydrogenation of the aldehyde group (BHMF) and also of the furanic ring (BHMTHF), as reported in Scheme 1.…”

5‐hydroxymethylfurfural (HMF), one of the most significant biomass‐derived renewable resources, has been widely utilized to create furan‐based value‐added chemicals such as 2,5‐diformylfuran (DFF), 5‐hydroxymethyl‐2‐furancarboxylic acid (HMFCA), 5‐formyl‐2‐furancarboxylic acid (FFCA), and 2,5‐furan dicarboxylic acid (FDCA). Indeed, DFF, HMFCA and FFCA are key intermediate products during the oxidation of HMF to FDCA. Herein, this review aims to demonstrate the recent advances in metal‐catalyzed oxidation of HMF into FDCA via two different reaction routes (HMF‐DFF‐FFCA‐FDCA and HMF‐HMFCA‐FFCA‐FDCA). All the four furan‐based compounds are comprehensively discussed by the selective oxidation of HMF. Additionally, various metal catalysts, reaction conditions, and reaction mechanisms used to obtain the four different products are systematically reviewed. It is anticipated that this review will provide related researchers with new perspectives and speed up the development of this field.

“…In this case, the nitrogen sites provided anchoring for metals and favored HMF adsorption. [26] Megías-Sayago et al [27] and Saxena et al [28] respectively managed to develop very efficient catalytic systems able to work in mild temperature conditions (60-70 °C). While in the first example a simple Au/Al 2 O 3 catalytic system prepared by the direct anionic exchange was studied, in the second one Saxena et al developed metal nanoparticles encapsulated into hollow zeolites.…”

Current Advances in the Sustainable Conversion of 5‐Hydroxymethylfurfural into 2,5‐Furandicarboxylic Acid

2,5-Furandicarboxylic acid (FDCA) is currently considered one of the most relevant bio-sourced building blocks, representing a fully sustainable competitor for terephthalic acid as well as the main component in green polymers such as poly(ethylene 2,5furandicarboxylate) (PEF). The oxidation of biobased 5hydroxymethylfurfural (HMF) represents the most straightforward approach to obtain FDCA, thus attracting the attention of both academia and industries, as testified by Avantium with the creation of a new plant expected to produce 5000 tons per year. Several approaches allow the oxidation of HMF to FDCA. Metal-mediated homogeneous and heterogeneous catalysis, metal-free catalysis, electrochemical approaches, light-mediated procedures, as well as biocatalytic processes share the target to achieve FDCA in high yield and mild conditions. This Review aims to give an up-to-date overview of the current developments in the main synthetic pathways to obtain FDCA from HMF, with a specific focus on process sustainability.
