Conversion of Acetophenone to Phenol
To convert acetophenone to phenol, the following steps can be followed:
Step 1: Reaction with meta-Chloroperbenzoic acid (m-CPBA)
Acetophenone can be reacted with m-CPBA to form a peroxyacid ester intermediate. This reaction is known as the Baeyer-Villiger oxidation. The peroxyacid ester intermediate can then be hydrolyzed to form phenol.
Step 2: Base-Catalyzed Hydrolysis
The peroxyacid ester intermediate formed in step 1 can be hydrolyzed by a base catalyst to form phenol. The base-catalyzed hydrolysis helps in breaking the ester bond and releasing phenol as the final product.
Explanation of the Correct Answer: Option A
The correct answer is option A, which involves the use of m-CPBA followed by base-catalyzed hydrolysis. This approach is commonly used to convert acetophenone to phenol because it allows for a selective and efficient conversion.
The m-CPBA oxidizes the acetophenone to form a peroxyacid ester intermediate. This intermediate can then be hydrolyzed by a base catalyst to yield phenol as the final product. This method is preferred over other options because it provides a straightforward and reliable route to phenol.
Other Options:
Option B: Concentrated nitric acid (HNO3) is a strong oxidizing agent but it may lead to overoxidation and the formation of undesired products.
Option C: Iodine and NaOH are not commonly used for the conversion of acetophenone to phenol.
Option D: Singlet oxygen followed by base-catalyzed hydrolysis is not a commonly used method for this conversion.
Overall, option A is the most suitable and commonly used approach for converting acetophenone to phenol.
