First, 5-amino-2,4,6-triiodobenzoic acid is used as the starting material. The benzoic acid is first reacted with chlorination reagents such as sulfinyl chloride or oxalyl chloride. When thionyl chloride reacts with benzoic acid, the sulfur atom is nucleophilic and can attack the carboxyl carbon atom to form an intermediate transition state.

If the temperature is too high or the reagent is too high, it may cause side reactions to occur, which will affect the purity and yield of the product.
Second, start from 5-nitro-2,4,6-triiodobenzene-1,3-dicarboxylic acid. The nitro group is first reduced to an amino group, and reduction reagents such as iron powder, zinc powder and hydrochloric acid system are commonly used, or catalytic hydrogenation methods. The nitro group obtains electrons under these conditions and is gradually converted into an amino group. After that, a chlorination reaction is carried out, which interacts with the above chlorination reagents to convert the carboxyl group into an acyl chloride group, thereby obtaining the target product. This path involves a one-step reduction reaction, and the process is slightly more complicated, but the starting material may be easier to obtain.
Third, a suitable benzene ring derivative is used as the starting material, and the target molecule is constructed through a multi-step reaction such as halogenation, nitration, reduction, and acylation. First, the benzene ring is halogenated to introduce iodine atoms; then nitrified to locate nitro groups; then the nitro group is reduced to amino groups; finally, acylation forms dicarbonyl dichloride. Although there are many steps in this route, the reaction conditions and intermediates are properly controlled, and the product with high yield and purity can
