：硫族键合 (ChB) 是作为路易斯酸位点的硫族原子与能够通过孤对电子或 p 电子充当路易斯碱的原子或原子团之间发生的非共价相互作用。与它的姐妹卤素键类似，这种相互作用的高方向性是为了在固态和溶液中实现精确的结构组织而实现的。关于催化作用，ChB 现在被认为是一种新的激活模式，过去五年中越来越多的例子证明了这一点。在 ChB 催化剂系列中，基于碲的催化剂似乎迅速超越了较轻的硫和硒催化剂。在这篇综述中，我们重点介绍了溶液中碲基衍生物的路易斯酸性质，并总结了它们在催化领域应用的最先进技术。
: Chalcogen bonding (ChB) is the non-covalent interaction occurring between chalcogen atoms as Lewis acid sites and atoms or groups of atoms able to behave as Lewis bases through their lone pair or p electrons. Analogously to its sister halogen bonding, the high directionality of this interaction was implemented for the precise structural organization in the solid state and in solution. Regarding catalysis, ChB is now accepted as a new mode of activation as demonstrated by the increased number of examples in the last five years. In the family of ChB catalysts, those based on tellurium rapidly appeared to overcome their lighter sulfur and selenium counterparts. In this review, we highlight the Lewis acid properties of tellurium-based derivatives in solution and summarize the start-of-the-art of their applications in catalysis.
