A general and robust transition-metal-catalyzed Pauson-Khand reaction is still difficult to achieve. In this contribution, we describe our recent observations on the effect of lithium chloride on Pauson-Khand reactions catalyzed by palladium(II) chloride-tetra­methylthiourea; this allows structurally diverse cyclopentenones to be prepared effectively.
