Abstract:
The reaction of molecular bromine in water catalyzed by micellar solution of sodium dodecyl sulfate (SDS) at room temperature with several aromatics instantaneously resulted in high-yield conversion to the industrially important mono-, di-, and tribrominated aromatic intermediates in excellent yields (91–99%) and purity (>99%). A simple workup procedure and the recovery of surfactant have been described. The entire process uses no organic solvent and generates absolute zero effluent and is, therefore, a ‘green’ alternative for the industrial bromination.
