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

Respuesta :

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

The both reactions involve ketone groups on which the nucleophile attacks.

What is a nucleophilic acyl substitution reaction ?

A nucleophilic acyl substitution reaction is one in which the acyl group is attacked by a nucleophile leading to a substition on the acyl carbon as shown on the both mechanisms.

The mechanims of the both reactions are shown in the image attached here. The both reactions involve ketone groups on which the nucleophile attacks.
