Introduction
ethynylmagnesium chloride is an organometallic compound with the chemical formula C2H2MgCl. It is a colorless solid, soluble in ether and alkane solvents.
ethynylmagnesium chloride are often used in organic synthesis reactions, such as Grignard reaction and Soxhaft synthesis reaction. It can be used as a carbon-seeking electron reagent and react with other compounds to generate carbon-carbon or carbon-functional group bonds.
A common method of preparing ethynylmagnesium chloride is by reacting sodium acetylide with magnesium chloride in an anhydrous environment. First, sodium acetylide is reacted with an anhydrous solvent (e. g., dry ether) to form sodium acetylide. Ethynyl sodium is then reacted with magnesium chloride to produce ethynylmagnesium chloride.
Regarding safety information, ethynylmagnesium chloride is a deliquescent substance and should be stored in a dry environment. It gradually decomposes in air and water, producing toxic gases. Therefore, appropriate protective equipment such as gloves and goggles should be worn when used in a work environment. In addition, ethynylmagnesium chloride should be stored in sealed containers, away from fire and oxidizing agents.
