概要
- 論文の詳細を見る
An imidazolium-based ionic liquid with cyclophane-type planar chirality was synthesized in an optically pure form for the first time. The resultant ionic liquid existed as a liquid at room temperature (Tg = –35 ˚C), and was found to be applicable as an NMR chiral shift reagent for racemic anions. Excellent robustness of the ionic liquid to a highly elevated temperature (270˚C) was proved from the viewpoints of isomerization and thermal decomposition.
