This is the first report on the selective synthesis of fulvenes via a [2+2+1] cyclotrimerization of alkynes under catalytic conditions. The reactions of aliphatic terminal alkynes 1a-e in the presence of a palladium catalyst in toluene gave the cyclotrimerization products 2a-e, not easily available
