PURPOSE:To carry out hydrolytic reaction of iodobenzene under mild condition and advantageously obtain the titled substance in high selectivity without problems in corrosion of an apparatus, etc., by using the iodobenzene as a raw material and adding a catalyst and iodine anion capturing agent to a reaction system. CONSTITUTION:Iodobenzene is hydrolyzed in the presence of a catalyst (preferably a copper or iron compound used in a molar amount of preferably about 0.1-10 times based on the iodobenzene) and iodine anion capturing agent, preferably at 150-250 deg.C to afford the aimed compound. A caustic alkali or aliphatic carboxylic acid salt is preferred for the iodine anion capturing agent and acetate is particularly preferred among them. The molar amount thereof to be used is about 1-20 times based on the iodobenzene. The pH of the reaction solution varies with the iodine anion capturing agent to be used and is preferably weak acidic - alkaline for an aliphatic carboxylic acid salt and phosphate. |
