6,7-dibromo-2,3-dicyanonaphthalene was synthesized from o-xylene by three steps:electrophilic aromatic substitution, free radical halogenation and electroclic reaction. The optimal synthetic conditions were obtained by the yield of target product 6,7-dibromo-2,3-dicyanonaphthalene could reach to 92. 9 %, and the cost of the product was decreased. The product was characterized by melting point, element analyses and IR spectra.
