Caught in the act: The [(dibenzosuberenol)Co2(CO)6] cluster 1 (see scheme) loses a carbonyl ligand to yield 2, the first structurally characterized alkyne-dicobaltpentacarbonyl-alkene complex. This finding provides experimental support for the first step of the proposed mechanism of the Pauson-Khand reaction and yields crucial structural data relevant to computational studies of the process.

The hexacarbonyldicobalt complexes of a range of 5-alkynyl-5H-dibenzo[a,d] cycloheptenes, 11a - e, readily undergo loss of a carbonyl ligand with concomitant formation of pentacarbonyldicobalt clusters, 12a-e, in which the vacant coordination site on coba
