METHOD FOR PRODUCING DIFLUOROBENZYL BROMIDE DERIVATIVE AND DIFLUOROBENZYL ETHER DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide methods for producing a difluorobenzyl ether derivative useful as a liquid crystal material and a difluorobenzyl bromide derivative that is an intermediate for the above derivative with which the formation of by-products can be suppressed and both the derivatives can simply and efficiently be produced. SOLUTION: The method for producing the difluorobenzyl bromide derivative comprises a step of reacting a benzene derivative with a base and then reacting a mixture of dibromodifluoromethane with bromodifluoromethane. The method for producing the difluorobenzyl ether derivative comprises a step of reacting the difluorobenzyl bromide derivative with a phenol derivative. COPYRIGHT: (C)2003,JPO
