We present the synthesis and thorough characterization of ionic liquids and organic saltsbased on hydrochalcogenide HE− (E=S, Se, Te) anions. Our approach is based on halide‐, metal‐, and water‐free decarboxylation of methylcarbonate precursors under acidic conditions, resulting from the easily dissociating reagents H2E. The compounds were characterized by elemental analysis, multinuclear NMR spectroscopy

The reaction of H2S with methylcarbonate salts allows access to pure hydrosulphide ILs, which show an astoundingly high volatility below 100 °C allowing high-end purification and ionic single crystal growth by sublimation.

In an attempt to produce new functionalized ionic liquids, a series of thiosalicylate ionic liquids based on imidazolium, ammonium, phosphonium, choline and pyrrolidinium cations were synthesized. The compounds were characterized by Infra Red (IR), Nuclear Magnetic Resonance (NMR) and mass spectra (ESI-MS). Their glass-transition temperatures, melting points and decomposition temperatures have been measured. Physicochemical properties of ionic liquids are influenced by alkyl chain length and nature of the cation of ionic liquids.
