Why does diethyl ether stabilize the Grignard reagent?
Diethyl ether prevents oxygen and carbon dioxide from reacting with the Grignard reagent once it is formed. Diethyl ether stabilizes the reagent, because the slightly negative oxygen on each end of the molecule is attracted to the slightly positive magnesium components of the Grignard molecules.
How does Grignard make triphenylmethanol from benzophenone?
The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product.
What kind of reagent is the dye crystal violet?
The Grignard reagent is readily prepared from 4-bromo-N,N-dimethylaniline. Addition of this Grignard reagent to diethyl carbonate, followed by acid hydrolysis gives the triarylmethane dye Crystal Violet. Addition of the Grignard reagent to methyl benzoate, followed by acid hydrolysis gives the dye Malachite Green.
How is the Grignard reagent formed in a reaction?
The Grignard reagent is formed by the reactions between an alkyl or aryl-halide and magnesium. The reaction proceeds via a radical electron transfer. Iodine can also be added to the reaction. The iodine lies on the magnesium and acts a catalyst to help initiate the reaction. Scheme 1. Formation of the Grignard reagent.
