Description

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.

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.
