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.

封面功能：使用ppm级催化剂负载量实现酮的氰基硅烷化的非共价硫族元素键合催化（Asian J. Org。Chem。5/2020）

由于非共价硫族元素键相互作用相对较弱，因此以有效方式实施硫族元素键催化仍然是一个真正的挑战。通过一类非凡的催化剂，证明了即使在数分钟内完成反应时，即使使用低至ppm级的催化剂载量，也可以实现酮氰基硅烷化的双重硫族元素键合催化方法。这种极其有效的催化方法显示了硫族元素键相互作用的独特优势，并证明了这种催化概念的潜力。有关更多信息，请参见Yao Wang等的《通讯》。
