通过对金卡宾结构解析的最新进展以及金属卡宾和类卡宾的定义进行综述，建议用金卡宾来描述金卡宾类中间体，而不考虑卡宾或碳阳离子极端共振占主导地位。金卡宾，由于弱的金属-卡宾π-反馈和它们的强亲电反应性，可以被分类为更广泛的Fischer卡宾家族，尽管它们的行为和性质非常特殊。
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.
