Triphenylmethanol can also be prepared by reacting ethyl benzoate with phenylmagnesium bromide, and by reacting diethylcarbonate
with phenylmagnesium bromide. Write stepwise rxn mechanisms for these two reactions
1 answer:
Answer:
Both reactions proceeds through nucleophilic acyl substitution reaction
Explanation:
- Both these two reactions proceeds through nucleophilic acyl substitution reaction where phenyl magnesium bromide replaces one ethoxide ion.
- Then another another equivalent of phenyl magnesium bromide give nucleophilic addition reaction with resulting keto group to produce triphenylmethanol
- Full reaction mechanism has been shown below
