Phenylmagnesium bromide is a Grignard reagent.It is often used as a synthetic equivalent for the phenyl "Ph −" synthon. Ethyl methyl ketone reacts with excess ethyl magnesium bromide to give tertiary hexyl alcohol. Not in a nucleophilic attack, no. J-802243 Magnesium bromide IS a molecule, or more correctly, it is a formula unit. Bromomethane is a manufactured chemical. A solution of 50.8g of 2,2-Diphenyl-3-methyl-4-dimethylaminobutyronitrile in 40ml of hot anhydrous xylene (~65°C) was added to a stirred solution of ethyl magnesium bromide (prepared from 8.8 grams of magnesium and 44 grams of ethyl bromide) in 60ml of anhydrous ethyl ether, and the mixture thereafter heated under reflux for 3 h. It is a colorless, nonflammable gas with no distinct smell. CH3COC2H5 +C2H5MgBr —→CH3CHOH(C2H5)2.+MgBrOH.
In anhydrous reaction conditions, the formation of Grignard reagents can occur when the reagent is reacted with an organic halide.
