Abstract
- The Molybdate-catalyzed bromination of various aromatic compounds in the presence of KBr/H 2 O 2 in an aqueous/chloroform biphasic system occurred under ultrasonic irradiation, whereas the reaction did not take place under conventional mechanical stirring (1400 rpm). The sonochemical activation was found to be of secondary effect, attributed to lowering pH by sonolysis of CHCl 3 –H 2 O solvents mixture.
