Following previously reported iodination of resorcinol and resorcylic acid derivatives, iodination of p-orsellinic acid, one of the carboxylic acids of orcinol, was carried out. For the iodination of p-orsellinic acid, iodine-potassium iodide solution was added at ordinary temperature to the phosphoric acid disodium phosphate solution (pH 2.50) of p-orsellinic acid and the mixture was allowed to stand for two hours. Diiodo-p-orsellinic acid was obtained in quantitative yield as slightly yellowish white crystals, m.p. 179-180° (decomp.). Its diacetate formed white needles, m.p. 157-160° (decomp.). Both these substances are new compounds.
