Application

Lithium perchlorate (LiClO4) may be used as a catalyst in the synthesis of bis(indolyl)methanes.

Lithium perchlorate may be used to catalyze:
• The acylation of hindered alcohols and phenols under solvent-free conditions.
• 1,4-Conjugate addition of O-silylated ketene acetals to hindered αβ,-unsaturated carbonyl system.
• The protection of amine groups as N-Boc derivatives via tert-butoxycarbonylation.
• Synthesis of α-aminophosphonates under solvent free conditions.

When used as a co-catalyst, accelerates the Baylis-Hillman reaction, the coupling of α,β-unsaturated carbonyls with aldehydes.

General description

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