The synthesis of 1-bromo-3-fluoro-4- (trifluoromethoxy) benzene is a key research in the field of organic synthesis. To obtain this compound, there are various common ways.
One of them can be started from phenolic compounds. First, a phenol containing a suitable substituent is introduced into bromine and fluorine atoms through a halogenation reaction with a suitable halogenating agent, such as a brominating agent and a fluorinating agent. Subsequently, the phenolic hydroxyl group is converted into a trifluoromethoxy group.
