由于非共价硫族元素键合相互作用相对较弱，因此以有效的方式实施硫族元素键合催化仍然是一个真正的挑战。通过一类特殊的催化剂，证明了即使使用低至ppm水平的催化剂负载，也可以实现酮的氰基硅烷化的双硫属元素键合催化方法，同时反应在几分钟内完成。这种极其有效的催化方法显示了硫族元素键合相互作用的独特优势，并展示了这种催化概念的潜力。更多的信息可以在Yao Wang等人的通讯中找到。
As noncovalent chalcogen-bonding interaction is comparatively weak, it remains a true challenge to implement chalcogen-bonding catalysis in an efficient manner. Enabled by a class of extraordinary catalysts, it was demonstrated that a dual chalcogen-bonding catalysis approach to the cyanosilylation of ketones can be achieved even using as low as ppm-level catalyst loading while the reactions were completed within several minutes. This extremely efficient catalysis approach shows the unique advantage of chalcogen-bonding interactions and demonstrates the potential of this catalysis concept.
