A series of symmetrical aromatic diketones were synthesized by the coupling reaction of bisorganozinc iodides and acyl chlorides in the presence of cuprous cyanide and lithium chloride in tetrahydrofuran at －25 ℃. The structures of the products were characterized by IR, 1H NMR, 13C NMR, MS techniques and elemental analysis. This method has the advantages of shorter reaction steps, good yields and simple work-up procedures, which is a new and efficient method for synthesis of long chain diketones.

Key words: bisorganozinc iodide reagent, acyl chloride, diketone
