Abstract

By reviewing the recent progress on the elucidation of the structure of gold carbenes and the definitions of metal carbenes and carbenoids, we recommend to use the term gold carbene to describe gold carbene-like intermediates, regardless of whether the carbene or carbocation extreme resonance dominates. Gold carbenes, because of the weak metal-to-carbene π-back-donation and their strongly electrophilic reactivity, could be classified into the broader family of Fischer carbenes, although their behavior and properties are very specific.

摘要

通过回顾在阐明金卡宾结构以及金属卡宾和类卡宾定义方面的最新进展,我们建议使用“金卡宾”一词来描述类似金卡宾的中间体,无论卡宾或碳正离子极限共振何者占主导。金卡宾由于金属到卡宾的π-反馈给电子作用较弱且具有很强的亲电反应性,尽管其行为和性质非常特殊,但仍可归类于更广泛的费舍尔卡宾家族。
