Allylmagnesium bromide is a
Grignard reagent used for introducing the
allyl group. It is commonly available as a solution in
diethyl ether
Diethyl ether, or simply ether, is an organic compound in the ether class with the formula , sometimes abbreviated as (see Pseudoelement symbols). It is a colourless, highly volatile, sweet-smelling ("ethereal odour"), extremely flammable li ...

allyl bromide
Allyl bromide (3-bromopropene) is an organic halide. It is an alkylating agent used in synthesis of polymers, pharmaceuticals, synthetic perfumes and other organic compounds. Physically, allyl bromide is a colorless liquid with an irritating and p ...
while maintaining the reaction temperature below 0 °C to suppress formation of hexadiene. Allyl chloride can also be used in place of the bromide to give allylmagnesium chloride.
These reagents are used to prepare
metal allyl complexes.
