-
A novel bromination method for T-H in alkylbenzenes using KBrO3/NaHSO3 as bromination agent and under an incandescent light illumination is reported. The method has advantages of mild reaction condition, simple operation, high utilization of bromine and avoidance of the erosive HBr gas. For some alkylbenzenes, especially some alkylbenzenes with a second substituent in benzene ring, the method provides brominated products of high yield and purity only at temperature usually of 50~55℃ under light illumination.
