There is disclosed a process for converting 2,2', 4,4', 6,6'-hexanitrobibenzyl (HNBB) to 2,2', 4,4', 6,6'-hexanitrostilbene (HNS) in high yields by reacting HNBB with a halogenating agent in the presence of a base in an organic solvent or a liquid suspending agent. A preferred halogenating agent is bromine; a preferred base is pyridine; a preferred solvent is dimethylformamide; and a preferred liquid suspending agent is toluene or chlorobenzene.
