ABSTRACT:
Cetyltrimethylammonium bromide (CTAB) micelle has been found its use for efficient and selective bromination reactions with phenols, anilines and acetanilides have been carried out under solvent free conditions. A mixture of metal salt (Zirconyl Nitrate and Ammonium molybdate), organic substrate and KBr or KBrO3 are taken in a mortar and grounded with a pestle at room temperature till the reaction is completed. The reactions afforded bromo derivatives in fairly good yields when a mixture of substrate with metal salt-KBr or metal salt-KBrO3 is used as brominating reagent instead of classical reagent KBr-KBrO3. Reaction times reduced significantly under solvent–free conditions when compared with solution phase reactions under reflux conditions.
