New double annulation reactions of 1,5-diynes with activatedalkenes are catalysed by cobalt(0) complexes, and can also occur in the absence of cobalt to give new classes of compounds, containing exocyclic double bonds, if terminal methyl groups are present on the triple bonds.

The reactivities towards triple and double bonds of some new cobaltacyclopentadiene complexes, derived from cobalt(O) and cobalt(I) complexes, have been compared. Their different abilities to undergo dissociation of ligands and the different stabilities of the resulting complexes account for the lower reactivity of cobalt(I) towards activated olefins. The crystal structure of a cyclopentadienylcob
