Procedure
In 100 cc of carbon tetrachloride is dissolved 3.1 g of 1,7-octadien-3-ol, followed by addition of 10 g of activated manganese dioxide. The mixture is stirred at room temperature for 4 days. The reaction mixture is filtered and the solvent is distilled off under a reduced pressure of 20-30 mm Hg. As a fraction at 30°-32° C./4 mm Hg, there is obtained 2 g of 1,7-octadien-3-one. The above fraction is identified to be 1,7-octadien-3-one by the following analyses.
