摘要:
The conversion of p-nitrobenzal bromide to p-nitrobenzotribromide, an intermediate in the preparation of the insecticide, 1,5-bis(4-trifluoromethylphenyl)-3-cyanoformazan, by reacting p-nitrobenzal bromide with an alkali or alkaline earth metal hypobromite is improved by carrying out the reaction in a two-phase, water-organic solvent system.
