How is triphenylmethanol synthesized in Grignard reagent?
When magnesium is added to the bromobenzene in ether, a Grignard reagent is formed. Using this Grignard reagent, triphenylmethanol can be synthesized in a two-step reaction first adding the reagent and then adding an acid.
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.
Which is a good reagent for the Grignard reaction?
The synthesis of a Grignard reagent was required for the Grignard reaction of this experiment to occur, therefore, phenylmagnesium bromide was produced before further proceeding with the preparation of triphenylmethanol. Grignard reagents, such as phenylmagnesium bromide, are Lewis bases and are good nucleophiles; they are also good leaving groups.
How to prepare Phenyl magnesium bromide using Grignard reaction?
Step 1: Assemble the microscale apparatus to be used during the preparation of phenyl magnesium bromide. Step 2: Label two clean, dry 3 mL conical vials “vial #1” and “vial #2”. Before proceeding to the next step, remember to quickly recap all of the reagents used in the experiment to ensure that there is no contamination from water vapor.
