Fe^III‐Based Eutectic Mixtures as Multi‐task and Reusable Reaction Media for Efficient and Selective Conversion of Alkynes into Carbonyl Compounds

Thanks to the use of a sustainable FeIII-based deep eutectic solvent (DES) as promoter/reaction medium, alkynes were hydrated under bench-type reaction conditions (45 °C, air, absence co-catalysts or co-solvents). This Fe-DES could be recycled for up eight consecutives runs in any VOC (E factor = 10). Furthermore, is able promote efficient formal oxidation internal into 1,2-diketones, with system being three consecutive times. More information can found Research Article by A.
