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-tetra-methylthiourea; this allows structurally diverse cyclopentenones to be prepared effectively.
仍然难以实现通用且稳健的过渡金属催化的 Pauson-Khand 反应。在这篇文章中,我们描述了我们最近对氯化锂对氯化钯(II)-四甲基硫脲催化的 Pauson-Khand 反应影响的观察;这允许有效地制备结构多样的环戊烯酮。
