An efficient synthesis of dibenzo[a,l]tetracene (1) and dibenzo[a,j]tetracene (2) has been developed using DielsAlder reaction of in situ generated ortho-quinodimethane with phenanthrene-1,4-dione, followed by reductive aromatization as key steps. This synthetic strategy resulted in good overall yield and the mixture of 1 and 2 is easily separable by reversed-phase liquid chromatography (RP-LC). Compounds 1 and 2 were identified in a complex mixture of polycyclic aromatic hydrocarbons from coal tar (Standard Reference Material 1597a)and thus could be potential environmental hazards.
