Question

The major product of the reaction is

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is B

To determine the major product of the given reaction, we need to analyze the reaction conditions and the mechanism involved.

1. The starting material is a diazo compound with the presence of a copper catalyst (CuSO₄). This suggests that the reaction involves the formation of a carbenoid intermediate.
2. The diazo compound loses nitrogen gas (N₂), generating a carbenoid. This is a common reaction known as the Wolff rearrangement.
3. The carbenoid then undergoes a rearrangement or insertion reaction leading to the formation of a more stable compound.
4. The presence of sulfur (SPh) and other functional groups can influence the stability and reactivity of the intermediate species.

Based on these steps, the major product is likely formed through a rearrangement or insertion process facilitated by the carbenoid intermediate.

The correct option represents the product formed via this mechanistic pathway.

Therefore, the major product of this reaction is as shown above.
