Background grignard reagents are highly excited organometallic reagents generated by treating alkyl group or aryl halides with magnesium metallic in the comportment of an anhydrous ether.
What are the reagents used in the Grignard reaction?
Grignard reaction allows the formation of carbon-carbon bonds using organometallic intermediate (Grignard reagents). Grignard reagents are prepared by reacting magnesium metal with alkyl or aryl halides in aprotic solvents such as diethyl ether or tetrahydrofuran.
How is triphenylmethanol synthesized from the Grignard reaction?
In this experiment, triphenylmethanol was synthesized from the reaction of the Grignard reagent (phenyl magnesium bromide) with benzophenone (a ketone) and hydrolysis with HCL. The final product was purified and characterized using TLC and IR spectroscopy. The final product was weighed and the percentage yield calculated.
How is bromobenzene used in the Grignard experiment?
In this experiment, bromobenzene is the alkyl halide used to generate Grignard reagent. Once the Grignard reagent is readily formed, the carbonyl compound has been introduced into the reagent in order to synthesis the expected product. The methyl benzoate (ester) acts as the carbonyl containing compound in the experiment.
How is triphenylmethanol prepared from benzophenone?
Triphenylmethanol is prepared from benzophenone using a Grignard reagent e.g. phenyl magnesium bromide through nucleophilic acyl addition mechanism. “Magnesium alkoxide is formed as an intermediate, which is then hydrolyzed by HCL to give an ether soluble triphenylmethanol and a water-soluble salt of MgBrCl” (Addison 446).
