Description
2-iodobenzoic acid and its derivatives are important pharmaceutical and chemical raw materials, which are necessary for the synthesis of various high-iodine reagents. It is commonly used as a precursor for the synthesis of 2-Iodoxybenzoic acid (IBX) and Dess-Martin peridinane, which are used as mild oxidants. It is also used in Suziki reaction.
Chemical Properties
white crystal powder
Application
2-Iodobenzoic acid can be used as a reactant in the synthesis of oligo(m-phenylene ethynylenes), (±)-lycoricidine and various detoxifiers of organophosphorus nerve agents. Additionally, it is used as a precursor in the preparation of oxidizing reagents like 2-iodoxybenzoic acid (IBX) and Dess-Martin periodinane (DMP).
Definition
ChEBI: An iodobenzoic acid with a single iodo substituent placed at the 2-position.
Preparation
2-Iodobenzoic acid is obtained from Anthranilic acid by diazotization and substitution. Diazotization of Anthranilic acid with sodium nitrite in the presence of sulfuric acid, control the temperature below 10℃, filter the diazotization solution, add the mixture of potassium iodide and sulfuric acid, stir for 10min after addition, and boil. Filter, wash with sodium thiosulfate solution, 2-Iodobenzoic acid can be recrystallized from water.
Purification Methods
Crystallise the acid repeatedly from water and EtOH. Sublime it under vacuum at 100o. [Beilstein 9 IV 1030.]
