WebMy understanding of the birch reduction mechanism (for now assume a messy shake n bake) is basically: Lye, lithium, and ammonia are combined in diethyl ether. A SMALL amount of water is added then vessel is "capped" to create pressure that is released occasionally to avoid explosions. The pressure "bronzes" lithium, which is evidence that a ...
