伦敦色散(LD)相互作用源于瞬间诱导的偶极子产生的长程电子关联，可以发生在相邻的原子或分子之间，例如，在配体C−H基团中的H原子之间。这些相互作用目前是一种稳定长键和具有不寻常氧化态的物种的新方法。它们还可以通过将LD增强的基团安装到有机骨架或配体取代基中来限制反应活性。在这里，我们讨论了LD增强配体设计的最新进展，可以产生的空间反直觉结构，以及这些相互作用可能对空间密集的重族 14物种的结构和反应活性的影响。
London dispersion (LD) interactions, which stem from long‐range electron correlations arising from instantaneously induced dipoles can occur between neighboring atoms or molecules, for example, between H atoms within ligand C−H groups. These interactions are currently of interest as a new method of stabilizing long bonds and species with unusual oxidation states. They can also limit reactivity by installing LD enhanced groups into organic frameworks or ligand substituents. Here, we address the most recent advances in the design of LD enhanced ligands, the sterically counterintuitive structures that can be generated and the consequences that these interactions can have on the structures and reactivity of sterically crowded heavy group 14 species.
