Acetic Acid → 2-Methyl-cyclohex-2-en-1-yl acetate

Participants

Reaction Steps

Acetoxylation of 1-methylcyclohexene A 500 ml three-neck flask is charged with 15 g of 1-methylcyclohexene (0.15 moles), 150 g of acetic acid, 0.77 g of benzoquinone (7 mmoles), 1 g of active charcoal and 80 mg of palladium acetate (0.35 mmoles). The temperature is taken to 50°, then 8 g (0.17 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 (75°-80°, 15×102Pa) to provide 2-methyl-cyclohex-2-en-1-yl acetate (11 g, yield 50%).
