The question asks: "Which one of the following reactions does not occur?" but the actual reaction options for A, B, C, D are missing in the prompt.

Because the reactions themselves are not provided, it is not possible to chemically evaluate which one does or does not occur.

Step-by-step analysis

1. For this type of organic chemistry MCQ, we must inspect each reaction option:

   • identify the substrate,
   • identify the reagent/conditions,
   • check whether the transformation is feasible.

2. However, the prompt shows:

   • A:
   • B:
   • C:
   • D:

   with no reaction content after them.

3. Therefore, there is insufficient information to derive the correct answer independently.

Comparison with stored answer

The stored correct answer is C, but since the reaction options are absent, I cannot verify whether option C is actually correct.

Conclusion

Please provide the reaction schemes/options A–D so that I can solve the question properly and verify the answer.
