Adapted from ref 62. 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 reduction mechanism begins with the formation of the radical anion by the addition of solvated electrons to the aromatic ring.
