4-iodobenzoic acid crystallization [4] X-ray crystallography of 4-iodobenzoic acid has shown that it crystallizes in the solid state as hydrogen-bonded dimers which stack perpendicular to their aromatic rings. The iodine atoms of adjacent dimers are also oriented towards each other due to van der Waals forces. [4]
Iodobenzoic acids are any of three organic compounds with the formula IC 6 H 4 COOH, consisting of a carboxylic acid group and an iodine atom bonded to a central benzene ring. They can be considered as iodinated derivatives of benzoic acid , or as carboxylated variants of iodobenzene .
Methyl 4-iodobenzoate, or methyl p-iodobenzoate, is an organic compound with the formula IC 6 H 4 COOCH 3. [3] It is the methyl ester of 4-iodobenzoic acid, or may also be viewed as an iodinated derivative of methyl benzoate.
In the first step, the amine functional group is diazotized with hydrochloric acid and sodium nitrite. Potassium iodide is added to the resultant phenyldiazonium chloride, causing nitrogen gas to evolve. The product is separated by steam distillation. [2] Alternatively, it can be produced by refluxing iodine and nitric acid with benzene. [3]
