SYNTHESIS OF HETEROCYCLES IN NON-CONVENTIONAL MEDIA: THE CASE OF IONIC LIQUIDS

2022

The synthesis of heterocycles is a prominent feature of organic chemistry, due to the enormous importance of such compounds in fields like medicinal or industrial chemistry. In the effort of improving their synthesis, the nature of the solvent plays a pivotal role. In this context, the use on non-conventional solvent like ionic liquids can determine significant improvements reaction outcomes, sustainability of the process, and possibility to be coupled with non-conventional synthetic methodologies, like ultrasounds or microwave irradiation. In this chapter, we present a bird’s-eye view on recent examples of the application of ionic liquids as solvents or catalysts, evidencing, whenever poss…

Highly recyclable surfactant-based supramolecular eutectogels for iodine removal

2022

In this work, we screened several surfactants for their ability to harden Eutectic Mixtures. We found cetyldiethanolamine-N-oxide as the best candidate, which was able to form eutectogel in four eutectic mixtures. Characterization of the gels obtained in terms of thermal stability, rheology and gelation kinetics, showed a prominent influence of the nature of the hydrogen bonding accepting and donating components for the first two parameter and the other one, respectively. Then, we assessed the eutectogels for their ability to adsorb I2, as a model for its radioactive nuclides, from apolar solvent solutions. The best performing gel allowed fast and thorough removal of I2, over a broad range …
