摘要：
The synthesis of isothiocyanato esters appended to (polyethylene glycol)-ionic liquid phases is reported. The starting task-specific ionic liquids (TSILs) were functionalized in good yields with bromoacetic acid or 4-chlorobutyroyl chloride by usual esterification reaction conditions. In the second step, the isocyanato esters appended to TSILs were obtained by displacement with potassium thiocyanate in refluxing anhydrous MeCN. The isothiocyanato-TSILs were characterized by NMR (H-1, C-13), mass spectrometry (MS) and IR spectroscopy.
