Abstract
A new method of preparation o-nitrobenzyl bromide using o-nitrotoluene as raw material, NaBrO3/NaHSO3 as bromination agent and AIBN as initiator was developed,under the optimum conditions n(o-nitrotoluene) ∶ n(sodium bromate) ∶ n(sodium bisulfite)=1 ∶ 4 ∶ 4,reaction terperature 70 ℃,reaction time 2 h,the yield is up to 73%. This process is easy to scale up with lower material cost,simple and convenient operation.
