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] WebThe Birch reduction 1–3 is still the de facto method for the production of cyclohexa-1,4-dienes, ... Under these conditions, methoxybenzene, in which the methoxy group is electron donating, is converted to 1-methoxycyclohexa-1,4-diene in 70 % yield and estrone methyl ether 9 affords 92 % yield of the reduction product [60].
