The reaction temperature can be lowered by neutralizing the polar solvent, but the reaction progresses easily only in the case of activated halogenated benzene, and with less active halogenated benzene, the target compound cannot be produced. Almost no gain.

用いなければならない。On the other hand, the Ullmann reaction is known, in which an alkali salt of phenol reacts with a halogenated benzene at high temperature in the presence of copper or a copper salt, but the reaction between dichlorobenzene and an alkali salt of chlorophenol, which have low activity, is known. , does not react even in the presence of copper or copper salts. In other words, it is thought that halogenated benzene has neither the ability to dissolve phenolate nor convert copper salt into a reactive form. Therefore, an example of adding chlorophenol in excess and using it as a solvent for the reaction (JP-A-49-62434+F
Although there is also i), the yield of diphenyl ether is not necessarily high. Furthermore, in the reaction of inert halogenated benzene, add a metal ion sequestering agent and let it react (time 1 id (
5G-29539), but it requires the use of an expensive metal sequestering agent.
