The synthesis of 1,2-dichloro-3- (trifluoromethyl) benzene is an important topic in the field of organic synthesis. To synthesize this substance, there are several common methods.
First, toluene is used as the starting material. First, toluene is halogenated. Under suitable conditions, chlorine atoms are introduced. Chlorine gas can be selected.
