Cover Feature: Gold Redox Catalysis with a Selenium Cation as a Mild Oxidant (Chem. Eur. J. 27/2020)

Year: 2020

Type: article

Abstract: Diselenide is demonstrated to function as a mild oxidant in gold-catalyzed alkyne diselenation reactions, which overcome the daunting high AuI/III redox potential (1.4 eV) depicted in the cover image as a ‘golden roller coaster’. Excellent trans- regioselectivity and good to excellent yields were achieved with a wide range of alkynes and allenes. Mechanistic investigation revealed the formation of a vinyl gold(I) intermediate followed by an intermolecular selenium cation migration, confirming a gold (I/III) redox process. More information can be found in the Communication by X. Shi et al. on page 5946.
