The invention provides ionic liquids having a secondary hydroxyl group, and an atom-efficient method for the preparation of these ionic liquids, by epoxidation of a protonated nitrogen- containing organic base (which can optionally be prepared in situ) in the presence of an anion suitable for supporting ionic liquid formation.
本发明提供了具有次级羟基的
离子液体,以及一种原子效率高的方法,用于制备这些
离子液体,方法是在适合支持
离子液体形成的阴离子存在下,通过氧化剂使质子化的含氮有机碱(可选地在原位制备)发生环氧化反应。
