We present the synthesis and thorough characterization of ionic liquids and organic salts based 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 H2 E. The compounds were characterized by elemental analysis, multinuclear NMR spectroscopy, thermal and single-crystal XRD analyses. The hydrosulfide salts were investigated with respect to their ability to dissolve elemental sulfur in varying stoichiometry. Thus-prepared polysulfide ILs were also analyzed by UV/Vis spectroscopy and cyclic voltammetry.
我们展示了基于硫氢化物HE⁻（E = S、Se、Te）阴离子的离子液体和有机盐的合成及全面表征。我们的方法基于碳酸甲酯前体在酸性条件下的无卤化物、无金属和无水脱羧反应，这是由易于解离的试剂H₂E引发的。通过元素分析、多核核磁共振光谱、热分析和单晶X射线衍射分析对这些化合物进行了表征。研究了硫氢盐溶解不同化学计量比元素硫的能力。还通过紫外/可见光谱和循环伏安法对如此制备的多硫化物离子液体进行了分析。
