For example, pesticides and pharmaceutical intermediates are prepared through substitution reactions, addition reactions, etc. In the synthesis of some new pesticides, 1,2,3-trichlorobenzene is used as the basic raw material, and through clever chemical transformation, the pesticides are endowed with unique insecticidal and bactericidal effects.

The method of preparing 1,2,3-tribromobenzene is to use benzene as the starting material and undergo a specific chemical transformation.
First, benzene is used as the raw material and brominated with bromine in the presence of an appropriate catalyst. The commonly used catalyst for this reaction is iron filings or iron tribromide. The reaction mechanism is that the bromine molecule is polarized under the action of the catalyst to form an active bromine positive ion. This bromine positive ion attacks the benzene ring and replaces the hydrogen atom on the benzene ring to form bromobenzene.
However, this reaction initially mainly generates monobromobenzene. To obtain 1,2,3-tribromobenzene, the reaction needs to be further carried out. Monobromobenzene can continue to react with bromine under the same catalytic conditions. The hydrogen atom on the benzene ring in monobromobenzene decreases the selectivity of the subsequent bromination reaction due to the blunt action of the bromine atom, resulting in the formation of various bromobenzene isomers. However, by controlling the reaction conditions, such as temperature, bromine dosage, reaction time, etc., the reaction can be carried out more in the direction of generating 1,2,3-tribromobenzene.
During the reaction process, temperature is crucial. Moderately increasing the temperature can speed up the reaction rate, but too high temperature may lead to more side reactions and more polybrominated by-products. The amount of bromine also needs to be precisely controlled. Adequate supply of bromine is a necessary condition for the generation of tribromobenzene, but excess bromine may cause waste of resources and separation difficulties.
After the reaction is completed, the product is a mixture of various bromobenzene, which needs to be carefully separated and purified. Commonly used separation methods include distillation, extraction, recrystallization, etc. Using the difference in the boiling point of each bromobenzene, it is initially separated by distillation; and then according to its solubility in different solvents, it is extracted and recrystallized to finally obtain pure 1,2,3-tribromobenzene.
