%X Condensation of seven aromatic aldehydes (1a&#8211;g) with glutacononitrile (2) gave 4-(arylmethylidene)pent-2-enedinitriles (3a&#8211;g). Flash vacuum pyrolysis of the dinitriles (3a&#8211;g) at 750&#176;/0&#183; 02&#8211;0&#183;03 mm gives annulated dihydroaromatic 1,3-dicarbonitriles by electrocyclic ring closure of (3). Fully aromatized products formed by secondary loss of H2 or HCN are also obtained.
