Procedure

Acetoxylation of l'hexa-1,5-diene ##STR3## A 500 ml three-neck flask is charged with 15 g of hexa-1,5-diene (0.18 moles), 150 g of acetic acid, 0.77 g of benzoquinone (7 mmoles), 1 g of charcoal and 80 mg of palladium acetate (0.35 mmoles). The temperature is taken to 50°, then 7 g (0.14 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 to provide 1-acetoxy-3-methylene-cyclopentane in 65% molar yield. 1-acetoxy-3-methylene-cyclopentane
