Abstract

PURPOSE: To readily obtain the titled compound in high purity and yield at a low cost without using an expensive reaction reagent and requiring a catalyst, by reacting an organic iodine compound with carbon monoxide and organic carboxylic acid salt.
CONSTITUTION: An organic iodine compound as a raw material is reacted with carbon monoxide and an organic carboxylic acid salt in the absence of a catalyst at ≥180°C, preferably at a temperature within the range of 200W400°C, more preferably within the range of 230W350°C and normally under a pressure within the range of 1W500kg/cm2, preferably within the range of 5W300kg/cm2 pressure to afford the aimed compound. The molar ratio of the organic iodine compound, e.g. a compound in which hydrogen in the aromatic ring of an aromatic hydrocarbon, e.g. benzene, etc., substituted by one or more I atoms, to the organic carboxylic acid salt is within the range of 0.5W2.0 equivalent iodine to the cationic component in the organic carboxylic acid salt.
