Merging Visible Light Photoredox and Gold Catalysis.

摘要: ConspectusSince the beginning of this century, π-Lewis acidic gold complexes have become catalysts choice for a wide range organic reactions, especially those involving nucleophilic addition to carbon–carbon multiple bonds. For most part, however, catalyst does not change oxidation state during course these processes and two-electron redox cycles kind implicated in cross-coupling chemistry are easily accessible. In order address limitation expand scope catalysis beyond conventional hydrofunctionalization, extensive efforts been made develop new oxidative reactions using strong external oxidants capable overcoming high potential AuI/AuIII couple. However, typically require superstoichiometric amounts oxidant proceed under relatively harsh conditions. Moreover, date, gold-catalyzed coupling remained somewhat limited because, many systems, desire...
