Abstract
We herein report a base-promoted generation of sterically hindered 1,3,5-triaryl 2-pyridylidene from the corresponding pyridinium salt. The thus-generated 2-pyridylidene was trapped by S(8) and Me(2)SAuCl to form 2-pyridinethione and a 2-pyridylidene-gold(I) complex, respectively. Rearrangement of pyridylidene to pyrido[1,2-a]indole indicates high reactivity of the carbene center of 2-pyridylidene.
摘要
我们在此报告了一种由相应的吡啶鎓盐引发的空间位阻的 1,3,5-三芳基 2-吡啶亚基的生成。生成的 2-吡啶亚基分别被 S(8)和 Me(2)SAuCl 捕获，形成 2-吡啶硫酮和 2-吡啶亚基金（I）配合物。吡啶亚基重排为吡啶并[1,2-a]吲哚表明 2-吡啶亚基的碳烯中心具有很高的反应活性。
