Touch, Pauson, engage: To explain the unique superior reactivity and stereoselectivity of O‐tethered enynes in asymmetric Pauson–Khand type reaction (APKR) than their congeners, the internal‐chelation to metal of oxygen atom of the substrate in the transition state was proposed. This proposition was well supported by APKR with several different substrates.
接触,鲍森,参与:为了解释在非对称鲍森-肯德型反应(APKR)中,O系链烯的独特反应性和立体选择性优于同类物,在过渡态下,底物对氧原子金属的内部螯合是建议的。APKR在几种不同的基材上很好地支持了这一主张。
