概要
- 論文の詳細を見る
The treatment of 1,1,1,3-tetrachloro-3-phenylpropane with alkali in ethanol affords ethynyl phenyl ketone and its acetal in good yields. This reaction proceeds through the elimination of hydrogen chloride and an efficient 1,3-proton transfer catalyzed by base. Ethyl cinnamate is obtained in only 2% yield.
