A new fulvene synthesis results from the palladium-catalyzed [2+2+2] annulation of 1 mol of a β-substituted vinyl iodide and 2 mol of a monosubstituted acetylene. This variant of the Heck reaction tolerates a wide range of substrate substituents with the best results obtained by using the catalyst, Pd(CH 3 CN) 2 Cl 2 . Addition of Cu I I to the reaction affords high yields of 1,3-enyne and no fulvene
