2,5-furandicarboxaldehyde (DFF) is one of the most promising biomass-based building blocks for synthesis biobased polymers. DFF can be obtained from 5-hydroxymethylfurfural (HMF), a fructose derivate, and it key molecule in sequence reactions furan chemistry to develop plastics. In this frame, four manganese(III)–Schiff base complexes 1–4 have been obtained. The general formula complexes, MnLn(OCN)(H2O/CH3OH)m (Ln being Schiff ligands L1–L4, formed as result condensation different substituted hydroxybenzaldehydes with diverse diamines, m = 1–3), has confirmed by characterization through analytical spectroscopic techniques. X-ray crystallographic studies 1 2 showed tetragonally distorted octahedral structures, where was placed equatorial coordination positions Mn(III) ion. Complexes behaved efficient catalysts oxidation HMF an electrolytic reaction at pH 8.5, phosphate buffer room temperature, conversion rates 70–80%. On other hand, 3 4, axial position sterically less accessible, yielded only 11% DFF. results indicate that correct selection metal allows development new way obtain
