This Perspective article highlights the recent development of mesoionic N-heterocyclic olefins (mNHOs), where the exo-cyclic olefinic carbon is not bonded to strongly electron-withdrawing groups. The unquenched basicity and nucleophilicity of the exo-cyclic olefinic carbon make mNHOs strong σ-donors and enable unique reactivity patterns.
这篇视角文章重点介绍了中离子型N-杂环烯烃(mNHOs)的最新进展,其中环外烯烃碳不与强吸电子基团相连。环外烯烃碳未被淬灭的碱性和亲核性使mNHOs成为强σ供体,并能产生独特的反应模式。
