Formylations of fluorine-containing aromatic compounds with dichloromethyl alkyl ethers have been investigated. Dichloromethyl propyl ether and dichloromethyl butyl ether have been applied for the formylation of fluorine-containing anisoles to give the corresponding aldehydes in good yields. Application of these ethers is preferable to that of methyl ether, which is prepared from volatile methyl formate. Reaction of fluorine-containing phenols with these dichloromethyl alkyl ethers did not give salicylaldehyde derivatives, leading instead to corresponding aryl formates in high yields. A plausible mechanism is discussed.

Paragraph 0004; 0032-0034, (2017/07/07)
The invention relates to a 3, 4 - difluoro toluene of continuous oxidation to prepare 3, 4 - difluorobenzaldehyde method, which belongs to the technical field of organic synthesis process. The method is characterized in that the 3, 4 - difluoro toluene compound as a raw material, cobalt, molybdenum, one or several of the bromine metal ion complex as catalyst, hydrogen peroxide as the oxidizing agent, acetic acid as solvent, in the tubular reactor continuous will be 3, 4 - difluoro benzene oxidation process for preparing 3, 4 - difluorobenzaldehyde process technology. Mild condition of this method, the reaction time is short, high utilization rate of raw materials, can be realized in the effective control of the reaction process, safe and stable, continuous operation, the production efficiency is high.
