Dual Chalcogen–Chalcogen Bonding Catalysis

The noncovalent S···O bonding interaction is an evolutionary force that has been smartly exploited by nature to modulate the conformational preferences of proteins. The employment of this type of weak noncovalent force to drive chemical reactions is promising yet remains largely elusive. Herein, we describe a dual chalcogen–chalcogen bonding catalysis strategy that the distinct chalcogen atoms simultaneously interact with two chalcogen-based...
