6-(Dimethylamino)fulvene reacted with 3- and 4-substituted 5-diazoazoles, as well as with 4-substituted benzene- and pyrazole-5-diazonium salts, in an aprotic solvent with high regioselectivity at an extremely high rate to give acyclic coupling products at the α-carbon atom of the cyclopenta-1,3-diene fragment. The nature of the diazo component did not affect the reaction direction, rate, or yield
