Procedure

A mixture of 450 g (4.6 mols) of potassium acetate and 637 g (3.6 mols) of 1-chloro-5-isopropoxy-3-methyl-2-pentene in 3000 cc of dimethylformamide is stirred at room temperature for 24 hours and then at 50°C for 4 hours. The reaction mixture is filtered, and solvent is distilled off at 1.4 mm Hg and the residue is fractionally distilled. A cis/trans mixture of 1-acetoxy-5-isopropoxy-3-methyl-2-pentene is obtained. B.P.: 122°-126° /18 mm Hg.
