A four-step procedure for the preparation of [U-14C]-1,3-dibromobenzene and [13C6]-1,3-dibromobenzene, from the corresponding bromobenzene, has been developed in a 30% yield. The products were isolated in a high specific activity, 2.6 GBq/mmol, and highest possible 13C incorporation. Copyright © 2011 John Wiley & Sons, Ltd.
