✦ Synopsis

This manuscript describes a silicon-tethered Pauson-Khand reaction and subsequent cleavage of the resulting vinyl silane to afford functionalized alkylidene cyclopentenones. Altering the reaction conditions affords a selective reaction with either p-bond of the allene.

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
