Abstract

The work describes the methylation of chiral and achiral imidazolinium-dithiocarboxylates. The resulting salts qualify as a novel class of ionic liquids after an anion metathesis was performed. Their NMR and UV/Vis spectra were studied.

Key words

ionic liquids - chirality - chiral cations - imidazolinium salts - zwitterions
