General description

Lithium perchlorate (LiClO4) is a colorless lithium salt. Upon crystallization from its aqueous solution, it affords lithium perchlorate trihydrate (LiClO4.3H2O). It can be synthesized by reacting lithium chloride with perchloric acid.

Application

Lithium perchlorate (LiClO4) may be used as a catalyst in the synthesis of bis(indolyl)methanes and in the Baylis-Hillman coupling reaction of α,β-unsaturated carbonyl compounds with aldehydes.
