WebCyclohexenone is an organic compound which is a versatile intermediate used in the synthesis of a variety of chemical products such as pharmaceuticals and fragrances. [2] It is colorless liquid, but commercial samples are often yellow. Industrially, cyclohexenone is prepared from phenol by Birch reduction. [3] WebAn example is the Birch reduction of the methoxybenzene portion of 514, which gave 515.Subsequent treatment with methanolic HCl converted the vinyl ether moiety in 515 to the ketone unit (via the enol) found in 516. Note that Birch reduction formed a trans ring juncture in 515 from the conjugated C=C unit in 514.
WebFeatures of Birch Reduction. Blue liquid results from the dissolution of alkali metals in liquid ammonia. Electrons are taken up one by one by aromatic rings. An ion is formed when the first electron is removed. Alcohol molecules form carbon-hydrogen bonds when their hydroxylic hydrogen is given away.
