When heated, allyl aryl ethers and allyl vinyl ethers undergo a reaction called a Claisen rearrangement, a concerted reorganization of bonding electrons similar to the Diels-Alder reaction. The reaction proceeds through a six-membered, cyclic transition state. Draw the structure of the expected product when this compound undergoes a Claisen rearrangement.

Transcribed Image Text:The image is a chemical structure of 4-Phenyl-2-butanone, commonly known as raspberry ketone.
**Chemical Structure Description:**
1. **Aromatic Ring**: The structure contains a benzene ring, which is a six-carbon ring with alternating double bonds.
2. **Ketone Group**: Attached to the benzene ring is a carbonyl group (C=O), indicating the presence of a ketone functional group.
3. **Butanone Chain**: Extending from the ketone, there is a butanone chain, which is a four-carbon chain. This chain includes the carbonyl group connected to a methyl group (CH3) and an ethyl group (C2H5).
Overall, the structure illustrates a combination of aromatic and aliphatic components, contributing to the molecule's distinct scent and applicability in flavorings.
