General description

Methylmagnesium bromide solution, also known as bromomethylmagnesium, is both a Lewis acid and nucleophile. It is commonly used as a grignard reagent in organic synthesis reactions.

Application

Methylmagnesium bromide solution (3M in diethyl ether) is used to synthesize:
  • 3S-(Boc-amino)-2,4-dimethyl-2-pentanol and methyl tert-butyl (S)-sulfoxide.
  • Methyl potassium polyimide (K-PIM-1) (MeMgBr).
  • 3(4R)-{3(2R,3S)-[4′-(1′-triphenylmethyl)imidazole]-2-bromo-1-oxobutyl)-4-phenyl2-oxazolidinone
  • Benzyl 2-(2-oxopropyl)piperidine-1-carboxylate
  • (R*, R*) 1-[1-(1-phenylethyl)pyrrolidin-2-yl]propan-2-one)

Packaging

The 25 mL Sure/Seal bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
