Method for producing compound having oxydifluoromethylene skeleton

摘要

An object of the present invention is to provide a method for producing a compound having an oxydifluoromethylene skeleton at a high yield by a simple process without using highly toxic starting materials, such as dibromodifluoromethane, while generating almost no difficult-to-separate impurities. A reaction between a thionocarboxylic acid ester (which may be obtained by a reaction between a halogenated thiocarbonyl compound and a specific compound as required) and a compound represented by Formula: XF n (wherein X represents chlorine, bromine, or iodine, and n represents a natural number of 1 to 5) gives a compound having an oxydifluoromethylene skeleton at a high yield. Various groups, such as an aromatic ring group, may also be introduced in high yield by reacting this compound with a boronic acid compound and the like as required.
