A new synthetic method to introduce chlorine atoms in aromatic rings by using hexachloroethane is proposed in this paper.At low temperature,the lithium(potassium) reagent is made from substituted aromatics.Then,this reagent reacts with hexachloroethane to obtain chlorinated aromatic hydrocarbons with high conversion rate.In this way,the synthesis of three different intermediates,which are ortho-no-fluorine atoms substituted,one fluorine atom substituent,double fluorine atom substituent,are studied.The products are characterized by mass and element analysis.The advantages of this method are high yield,good purity and lower cost,etc.
