Description

General description

Lithium bromide (LiBr) is a lithium salt. LiBr/Chlorotrimethylsilane reagent has been employed for the transformations of alcohols to bromides. LiBr/Ceric ammonium nitrate (CAN) reagent system has been used for the chemo- and regioselective bromination of aromatic compounds.

Application

Lithium bromide (LiBr) may be employed as a catalyst in the following studies:
• Solvent-free dithioacetalization of (aromatic- and α,β-unsaturated) aldehydes.
• Synthesis of olefins, via condensation reaction of carbonyl compounds with active methylene compounds.
• Synthesis of β-amino alcohols, via ring opening reaction of epoxides with amines.
