Web4. Explain the Birch reduction (The Birch reduction is an organic reaction that is used to convert arenes to cyclohexadicnes. In this Birch reduction, aromatic rings will form when a strong base is used (such as alkaline metal dissolved in liquid ammonia with and an alcohol. This Birch reaction is reduces the aromatic ring to a cyclohexane.): WebThe Birch Reduction - Baran Lab

Webimportant applications of the Birch reduction is the conversion of aryl alkyl ethers to 1-alkoxycyclohexa-1,4-dienes. These extremely valuable dienol ethers provide cyclohex-3-en-1-ones by mild acid hydrolysis or cyclohex-2-en-1-ones when stronger acids are used (Scheme 1).
