“…Replacing -NH 2 by -OH led to a series of monomeric and oligomeric MoO 2 L complexes (Figure 10) tested as catalysts using TBHP as an oxidant in water (W) or in decane (D) and no other added solvent [46]. Results are compiled in Table 7.…”

This article gives an overview of the research activity of the LAC2 team at LCC developed at Castres in the field of sustainable chemistry with an emphasis on the collaboration with a research team from the University of Zagreb, Faculty of Science, Croatia. The work is situated within the context of sustainable chemistry for the development of catalytic processes. Those processes imply molecular complexes containing oxido-molybdenum, -vanadium, -tungsten or simple polyoxometalates (POMs) as catalysts for organic solvent-free epoxidation. The studies considered first the influence of the nature of complexes (and related ligands) on the reactivity (assessing mechanisms through DFT calculations) with model substrates. From those model processes, the work has been enlarged to the valorization of biomass resources. A part concerns the activity on vanadium chemistry and the final part concerns the use of POMs as catalysts, from molecular to grafted catalysts, (ep)oxidizing substrates from fossil and biomass resources.

“…Since our research domain is the catalytic applications of oxo-molybdenum and oxo-vanadium coordination complexes [ 14 , 15 , 16 , 17 , 18 ] and POMs [ 19 , 20 , 21 ], such as molecular [ 19 , 20 ] or supported catalysts [ 21 ], with emphasis on biomass-based substrate valorisation [ 22 , 23 , 24 ], we proposed to edit this Special Issue with the aim of collecting research of other international groups within the domain to show the diversity of possible catalyzed reactions using metal complexes. High catalytic activity with relatively low metal loading is an asset, from relatively low cost to more sustainable processes.…”

Molybdenum complexes featuring acyl‐hydrazones ligands with several substitutions, H2L, have been synthesized using classic solution‐based, hydrothermal, and mechanochemical techniques in diverse solvent environments. Elemental analysis (EA), infrared attenuated total reflection spectroscopy (IR‐ATR), and thermal gravimetric analysis (TGA) helped to elucidate the structural and thermal properties of these complexes. Single‐crystal X‐ray diffraction (SCXRD) experiments were conducted to determine the crystal and molecular structures of one ligand and six mononuclear complexes, denoted [MoO2(L)(D)] (D= MeOH, EtOH, H2O). The catalytic potential of those Mo compounds was explored in the (ep)oxidation reactions of cyclooctene as model substrate and linalool as natural substrate issued from biomass, employing aqueous tert‐butyl hydroperoxide (TBHP) as an oxidising agent and no additional organic solvent. Experimental findings were complemented by theoretical density functional theory (DFT) calculations, establishing a correlation between experimental results and theoretical predictions. Insights gained from this comprehensive investigation shed light on the role of ligands in catalytic pathways for both cyclooctene and linalool oxidation, thereby advancing our better understanding of molybdenum‐based catalytic systems.
