特徴

• Lithium bromide (LiBr) may be employed as a catalyst in the following studies:
• Transformation of (aromatic- and α,β-unsaturated) aldehydes to dithioacetals via solvent-free dithioacetalization.
• Synthesis of olefins via condensation reaction of carbonyl compounds with active methylene compounds.
• Green synthesis of β-amino alcohols.
• Chemo- and regioselective bromination of aromatic compounds was carried out by employing LiBr/ceric ammonium nitrate (CAN) reagent system (as a source of Br+ ion).
