Here's the reaction equation:
C₆H₅COCl + CH₃COONa → C₆H₅COOCH₃ + NaCl
Mechanism:
1. Nucleophilic Attack: The acetate anion (CH₃COO⁻) from sodium acetate acts as a nucleophile and attacks the electrophilic carbonyl carbon of benzoyl chloride.
2. Leaving Group Departure: The chloride ion (Cl⁻) leaves the benzoyl chloride, as it is a good leaving group.
3. Formation of Phenyl Acetate: The acetate anion bonds to the carbonyl carbon, forming phenyl acetate.
4. Sodium Chloride Formation: The sodium ion (Na⁺) from sodium acetate combines with the chloride ion to form sodium chloride.
Conditions:
* The reaction typically occurs in an aprotic solvent like diethyl ether or dichloromethane, to prevent unwanted side reactions.
* The reaction is usually carried out at room temperature or slightly elevated temperatures.
Importance:
This reaction is important in organic synthesis as it is a way to introduce an acetyl group into a molecule. Phenyl acetate, the product, is used in various applications, including:
* Fragrances: It is used in perfumes and cosmetics.
* Flavorings: It contributes to the aroma of fruits and spices.
* Chemical intermediates: It is used as a starting material for the synthesis of other organic compounds.
