ABSTRACT:
The present invention discloses a process for the preparation of highly pure pentabromobenzyl bromide, PBB-Br, wherein the benzylic bromination reaction is carried out in a suitable organic solvent in the presence of water and wherein the reaction temperature is such that it is sufficient to activate the initiator but not high enough to consume a substantial amount thereof.
