Application

Ethynylmagnesium Bromide is a versatile reagent used primarily for its role in Grignard reactions. It's employed in a variety of synthetic processes, including the preparation of alkyne components for enyne cross-metathesis, which results in conjugated dienes. Additionally, it is used in the ethynylation of chiral α-(dibenzylamino) aldehydes and the synthesis of ethynyl aziridines. This reagent also aids in forming alkyl(triethynyl)germanes from tert-alkyltrichlorogermanes and 2-butyltrichlorogermane. Furthermore, it is instrumental in preparing key intermediates in the total synthesis of complex molecules like (+)-4-demethoxydaunomycin.
