Reaction Steps

Acetoxylation du cyclopentene A 500 ml three-neck flask is charged with 15 g of cyclopentene (0.22 moles), 150 g of acetic acid, 0.77 g of benzoquinone (7 mmoles) and 80 mg of palladium acetate (0.35 mmoles). The temperature is taken to 50°, then 12 g (0.25 moles) of 70% by weight hydrogen peroxide are introduced in 8 h, and the reaction is allowed to proceed for a further 2 h while maintaining the temperature at 50°. The acetic acid is then distilled (35°, 20×102Pa). The residue is distilled under vacuum (56°-60°, 15×102Pa) to provide cyclopent-2-en-1-yl acetate (13 g, yield 60%). cyclopent-2-en-1-yl acetate
