## Abstract Pauson–Khand reactions of functionalized allenes with different alkynes give cyclopentenones with generally high regio‐ and stereoselectivities. The allenes react through their external double bonds, giving cyclopentenones with exocyclic double bond at their β positions and predominantl

The regioselectivity of the cobalt-mediated cocyclisation of alkynes with allenic hydrocarbons leading to 4-and 5-alkylidenecyclopentenones was shown to depend on the substitution pattern of both the acetylenic and allenic components. An initial pseudoaxial coordination of the allenic hydrocarbon ma

## Abstract The carbonyldicobalt‐mediated alkyne/allene/CO cocyclization gives 4‐alkylidenecyclopentenones as the major [2+2+1] cycloadducts. The regio‐ and stereoselectivities depend mainly on the substitution pattern of both the alkyne and the allenic moieties, which can be rationalized using the
