Chemical Properties

clear brown to dark brown solution

Uses

Ethynylmagnesium chloride solution can be used:

• To synthesize 1-ethynyldeoxyribose derivatives which can further undergo Sonogashira coupling with various aryl, heteroaryl, and metallocenyl derivatives.
• In one of the key synthetic steps of substituted naphthostyrils.
• In the preparation of propargylic ester precursor for the synthesis of 1,3-dienylphosphonates.
