The invention relates to an oxidative coupling preparation of a phenanthrene derivative under catalysis of sodium nitrite. A product phenanthrene derivative (B) can be obtained by the steps of adding a (E)-1,2-bis(substituted phenyl)-vinyl derivative or a (Z)-1,2-bis(substituted phenyl)-vinyl derivative or a mixture with any ratio of E/Z mixture in an organic solvent, dissolving the above material, then adding a certain amount of trifluoroacetic acid, adding a catalytic amount of sodium nitrite added in one time, stirring at a temperature ranging from -30 DEG C to 80 DEC C until the raw materials are reacted completely, adding water, separating liquid, drying an organic layer and distilling off the solvent. A pure product can be obtained through recrystallization of the product.
