Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
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.

Solubility
Soluble in ethylene diamine, n-propyl amine, n-butyl amine, pyridine, dimethyl formamaide, diglyme, dioxan and dimethylsulfoxide.

Notes
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.
