CAS 65032-27-1: ethynylmagnesium chloride

Description: Ethynylmagnesium chloride, with the CAS number 65032-27-1, is an organometallic compound belonging to the class of Grignard reagents. It is characterized by the presence of a magnesium atom bonded to an ethynyl group (C≡C) and a chloride ion. This compound typically appears as a colorless to light yellow solution in organic solvents, such as diethyl ether or tetrahydrofuran. Ethynylmagnesium chloride is highly reactive, particularly with water and moisture, leading to the release of ethyne (acetylene) and the formation of magnesium hydroxide. Due to its nucleophilic nature, it is commonly used in organic synthesis for the formation of carbon-carbon bonds, enabling the preparation of various alkyne derivatives. The compound must be handled under an inert atmosphere to prevent decomposition and is typically stored in sealed containers to maintain its reactivity. Safety precautions are essential when working with this reagent, as it can be flammable and corrosive.
