Allyl vinyl ether is primarily used as an intermediate in organic synthesis, particularly in the preparation of more complex molecules through thermal rearrangements. It undergoes the Claisen rearrangement at elevated temperatures to form γ,δ-unsaturated carbonyl compounds, which are valuable building blocks in the synthesis of natural products and pharmaceuticals. Its ability to participate in pericyclic reactions makes it useful in the development of fine chemicals and specialty materials. Additionally, it serves as a precursor in the production of certain polymers and functionalized ethers, where its reactive double bonds allow for further chemical modifications. Due to its volatility and reactivity, it is handled with care in controlled environments for research and industrial applications.
