Examination was made of the acylation reactions of Δ2-carene (1) and Δ3-carene (2) with acid anhydrides (acetic anhydride and propionic anhydride) in the presence of synthetic zeolites.
The following results were obtained : In acetic anhydride and propionic anhydride with Y Type zeolites, the acylation of (1) gave 2-acetyl-3-carene (3) and 2-propionyl-3-carene (4) respectivery. In Y type Zeolites, 4-acetyl-2-carene (5) and 4-propionyl-2-carene (6) were obtained from (2) as the main products, respectively.
