A 500 ml three-neck flask was charged with 15 g of cyclohexene (0.18 moles), 150 g of acetic acid and 80 mg of palladium acetate (0.36 mmoles). The temperature was taken to 50°, and then 10.6 g (0.22 moles) of 70% by weight hydrogen peroxide were introduced in 8 h. The reaction was continued for 2 more hours, while keeping the temperature at 50°. The acetic acid was then distilled (35°, 20×102Pa). The residue was distilled under vacuum (64°-68°, 15×102Pa) to provide cyclohex-2-en-1-yl acetate, 90% pure (13 g, yield 50%). cyclohex-2-en-1-yl-acetate
