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.

Low cross-link density thermally reversible networks were successfully synthesized from jatropha and sunflower oils. The oils were epoxidized and subsequently reacted with furfurylamine to attach furan groups onto the triglycerides, preferably at the epoxide sites rather than at the ester
