应用
Lithium acetylide ethylenediamine complex is used in the synthesis of a chiral cyclopropanol. It is also used as an alkynylating reagent for the enantioselective alkynylation of ketones catalyzed by lithium binaphtholate without using other metal sources.

备注
Moisture and light sensitive. Store in cool place. Incompatible with alcohols, acids, oxidizing agents, water. It reacts with water to form lithium hydroxide and acetylene, which is a flammable gas. Over time, pressure may increase causing containers to burst. Handle and open container with care.
