“…In both cases, no reaction was observed. Inspired by the excellent results achieved in previous studies [32,38,39], a hydrophobic ionic liquid (i.e., [pmim]Tf 2 N 1-propyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide) was adopted as co-solvent. In fact, in the last years ionic liquids became a valid alternative to the conventional molecular solvents, due to their unique properties such as non-volatility, high thermal stability and reusability [40].…”

Thanks to the well-recognized role of benzaldehyde in industry, nowadays the research of new and sustainable approaches to selectively synthesize such an interesting product is receiving great attention from the chemists’ community. In this paper, a V-based catalytic biphasic system is adopted to perform toluene oxidation to benzaldehyde. Importantly, to pursue sustainability, organic solvents have been avoided, so toluene is used as substrate and co-solvent, together with water. Also, the use of hydrophobic ionic liquids has been explored. To perform oxidation, NH4VO3 catalyst, H2O2, and a safe and inexpensive co-catalyst are used. Among the tested co-catalysts, KF and O2 were found to be the best choice, to guarantee good yields, in mild reaction conditions. In fact, with such a sustainable method, up to 30% of benzaldehyde can be obtained at 60 °C and, more interestingly, the oxidative system can be recharged, raising-up the yield. The entire process results highly selective, since no traces of benzyl alcohol or benzoic acid are detected. Hence, it constitutes a very appealing synthetic route, even suitable to be easily scaled-up at an industrial level.

“…Finally, with the idea to further investigate the potentiality of our catalytic system, we decided to exploit the microwave irradiation as energy source for the ECODS, to optimize the reaction time as much as possible. On the other hand, the combination of microwave irradiation, as energy source, with ionic liquids, either as solvents or catalysts, has been largely investigated, in recent years [26].…”

“…1,3–12 There are dozens of specialised reviews on the use of ILs and derivatives in catalysis reported in the last decade. 13–37 We will concentrate on the possibilities and advantages that ILs and their derivatives may provide for green catalytic reactions as compared to classical molecular organic solvents or water. Indeed, ILs may offer the possibility of:…”
