WebHere, an organic reduction of aromatic rings in liquid ammonia with sodium, lithium or potassium and alcohol occurs. An example of a Birch reduction reaction is the reduction of naphthalene (illustrated below). Birch … 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 proton source (traditionally an alcohol). Unlike catalytic hydrogenation, Birch re…

WebThe Birch reduction [1] is a very powerful tool for the hydrogenation of benzene and its derivatives to yield the cyclohexa-1,4-dien compounds. It is performed in metal ammonia solutions (MAS, electron donator) with added alcohols (proton donator), e.g.: 2Li⁄2CH3OH ⁄C6H6)2LiOCH3 ⁄C6H8 –1ƒ The Birch reduction is in contrast to the ...
