Reaction Steps
A solution of 51 parts of p-nitrobenzal bromide in 500 parts of carbon tetrachloride is added to a solution of 80 parts of bromine plus 160 parts of 50% sodium hydroxide in 2,000 parts of water at 50° C. The mixture is stirred with a mechanical stirrer for 2.5 hours. The carbon tetrachloride layer is separated, dried and evaporated to give 58 parts (90% yield) of p-nitrobenzotribromide, m.p. 81-3° C.
