Select the correct Baeyer-Villiger oxidation reaction:

Options

A. a.
B. b.
C. c.
D. d.

Explanation

To solve the question regarding the correct Baeyer-Villiger oxidation reaction, we need to follow these steps:

### Step 1: Understand Baeyer-Villiger Oxidation
Baeyer-Villiger oxidation is a reaction where a ketone is converted into an ester in the presence of a peroxy acid. The reaction involves the addition of an oxygen atom to the carbonyl carbon of the ketone.

**Hint:** Remember that Baeyer-Villiger oxidation specifically involves ketones and peroxy acids.

### Step 2: Identify the Structure of Ketones
In a ketone, there are two alkyl groups attached to the carbonyl carbon. We can denote them as R and R'. The reactivity of these alkyl groups influences where the oxygen will be added.

**Hint:** Focus on the nature of the alkyl groups (primary, secondary, tertiary) when analyzing the reaction.

### Step 3: Determine Electron Richness of Alkyl Groups
The oxygen from the peroxy acid will preferentially attach to the side of the carbonyl carbon that has the more electron-rich alkyl group. The order of electron richness is:
- Tertiary > Secondary > Primary > Aryl

**Hint:** Recall that tertiary alkyl groups have a stronger +I effect than secondary or primary groups, making them more electron-rich.

### Step 4: Analyze the Given Reactions
1. **Reaction A:** Cyclohexanone treated with peroxy acid (H2SO5) forms caprolactam. This is a valid Baeyer-Villiger reaction.
2. **Reaction B:** A ketone with a tertiary alkyl group on one side and a phenyl group on the other. The oxygen will attach to the tertiary side, making this a valid Baeyer-Villiger reaction.
3. **Reaction C:** A ketone with hydrogen on one side and a phenyl group on the other. Here, the oxygen would incorrectly attach to the phenyl group instead of the hydrogen side, making this an invalid Baeyer-Villiger reaction.

**Hint:** Carefully evaluate the products formed in each reaction to determine if they align with the expected outcomes of Baeyer-Villiger oxidation.

### Step 5: Conclusion
From the analysis:
- **Option A** is correct.
- **Option B** is correct.
- **Option C** is incorrect.

Therefore, the correct Baeyer-Villiger oxidation reactions are **Option A and Option B**.

**Final Answer:** Options A and B are correct; Option C is not correct.
