Synthesis
There are many methods for synthesizing 1-chloro-2-iodobenzene. A more common method is achieved by halogenation of benzene rings. Using benzene as the starting material, first under specific reaction conditions, such as in the presence of a suitable catalyst and in a suitable reaction temperature and solvent environment, benzene and chlorine gas are substituted to introduce chlorine atoms to generate chlorobenzene. Then, p-chlorobenzene is reacted with an iodine source in a suitable reaction system, and the iodine atom replaces the hydrogen atom at a specific position on the benzene ring to obtain 1-chloro-2-iodobenzene. This synthesis route is relatively classical, but in the actual operation, the reaction conditions need to be strictly controlled to improve the purity and yield of the product. Another method may involve some more complex organic synthesis strategies, using organometallic reagents, etc., to gradually construct the target molecular structure through multi-step reactions. This method may have certain advantages in selectivity and reaction efficiency, but it requires more stringent reaction conditions and operation techniques.
