The use of the ionic liquid/ n ‐hexane interface as a new class of reaction medium for the Diels–Alder reaction gives large rate enhancements of the order of 10 6 to 10 8 times and high stereoselectivity, as compared to homogeneous media. The rate enhancement is attributed to the H‐bonding abilities and polarities of the ionic liquids, whereas the hydrophobicity of ionic liquids was considered to be the factor in controlling stereoselectivity.
