摘要

最近在分离掩蔽宝石碳化物方面取得的进展表明，这类物种可能比我们想象的更容易获得。这篇观点性文章总结了过去 140 年研究的里程碑，旨在为分离含有真正四价电子碳的物种指明方向。目前，供体配体的强中间体捐赠或配位被用来稳定此类阳离子。要在单个原子上实现两种电荷的真正定位，需要巧妙地结合感应捐献、超共轭和立体阻碍。

On the road to isolable geminal carbodications

Recent advances in the isolation of masked gem-carbodications have shown that such species may be more accessible than we thought. This perspective article summarizes the milestones of the last 140 years of research and aims to point the way toward the isolation of species containing true four-valence-electron carbon. Currently, strong mesomeric donation or coordination by donor ligands is used to stabilize such dications. Achieving true localization of both charges on a single atom will require smart combinations of inductive donation, hyperconjugation, and steric hindrance.
