The tetracyano double bridged maleic anhydride was prepared from a mixture of the diene anhydride (3), and tetracyanoethylene in tetrahydrofuran which give the white powdery adduct (8) in good yield,  via the diels-Alder reaction, and some new experiment models were carried out in order to complete a new approach for the synthesis of catena compounds.
