Description

General description

Lithium bromide (LiBr) is a lithium salt. LiBr/Chlorotrimethylsilane reagent has been employed for the transformations of alcohols to bromides.[1] LiBr/Ceric ammonium nitrate (CAN) reagent system has been used for the chemo- and regioselective bromination of aromatic compounds.[2]

Application

Lithium bromide (LiBr) may be employed as a catalyst in the following studies:

• Solvent-free dithioacetalization of (aromatic- and α,β-unsaturated) aldehydes.[3]
• Synthesis of olefins, via condensation reaction of carbonyl compounds with active methylene compounds.[4]
• Synthesis of β-amino alcohols, via ring opening reaction of epoxides with amines.[5]
