The Birch reduction is an organic reaction that is used to convert arenes to 1,4-Cyclohexadiene. The reaction is named after the Australian chemist Arthur Birch and involves the organic reduction of aromatic rings in an amine solvent (traditionally liquid ammonia) with an alkali metal (traditionally sodium) and a … See more A solution of sodium in liquid ammonia consists of the intensely blue electride salt [Na(NH3)x] e . The solvated electrons add to the aromatic ring to give a radical anion, which then abstracts a proton from the alcohol. The … See more Arthur Birch, building on earlier work by Wooster and Godfrey, developed the reaction while working in the Dyson Perrins Laboratory at the University of Oxford. Birch's original … See more • Solvated electron — the reducing agent • Bouveault–Blanc reduction — another reaction using solvated electrons • Synthesis of methamphetamine — an application See more Traditional Birch reduction requires cryogenic temperatures to liquify ammonia and pyrophoric alkali-metal electron donors. Variants have developed to reduce either inconvenience. Many amines serve as alternative solvents: for example, See more • Caine, D. (1976).

WebBirch-type reactions involve, among other chemicals, water reactive materials (WR) such as, but not restrictive to, sodium, potassium and lithium, and toxic gas such as ammonia. Those chemicals are covered by their specific class SOPs. Before setting-up a Birch-Type reaction, researchers must have read and sign the specific class SOPs of ...
