ETHYNYLMAGNESIUM BROMIDE 0.5M SOLUTION IN TETRAHYDROFURAN (C005B-039789)

General description

Ethynylmagnesium bromide solution, also known as bromoethynylmagnesium, is a grignard reagent that is commonly used in the synthesis of polymers, and unsaturated phosphonites.

Application

Ethynylmagnesium bromide solution can be used in:

• Grafting of aliphatic polymer.
• Synthesis of anthracene-containing species like 1,8-dichloro-10-(ethynyl)anthracene.
• The preparation of the alkyne component in an enyne cross-metathesis leading to conjugated dienes.
• Ethynylation of chiral α-(dibenzylamino) aldehydes.
• The synthesis of ethynyl aziridines.
• To prepare alkyl(triethynyl)germanes from tert-alkyltrichlorogermanes and 2-butyltrichlorogermane.
• The preperation of a key intermediate in the total synthesis of (+)-4-demethoxydaunomycin.
