When combined with magnesium metal in dry ether, it gives the corresponding Grignard reagent. Such reagents are used to attach butyl groups to various substrates. 1-Bromobutane is the precursor to n-butyllithium: [4] 2 Li + C 4 H 9 X → C 4 H 9 Li + LiX where X = Cl, Br. The lithium for this reaction contains 1-3% sodium.

Grignard reagents or Grignard compounds are chemical compounds with the general formula R−Mg−X, where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride Cl−Mg−CH 3 and phenylmagnesium bromide (C 6 H 5)−Mg−Br. They are a subclass of the organomagnesium compounds.

A splash guard prevents ingredients from flying out of the bowl, especially when adding dry ingredients or mixing at high speeds. "It keeps your workspace and mixer cleaner," Stewart says.
Reaction with magnesium, using diethyl ether as solvent, only gives about 25–30% of the cyclopropylmagnesium bromide Grignard reagent, with nearly as much cyclopropane formed by alternate reactions on the metal surface. [4] The compound isomerizes on heating to produce 1-bromopropene and 3-bromopropene. [5]
