Light‐Driven Single‐Electron‐Transfer Processes as an Enabling Principle in Sulfur‐ and Selenium‐Multicatalysis

Cooperativity has become a mainstay in the context of multicatalytic reaction design. The combination of two or more catalysts, possessing mechanistically distinct activation principles, within a single chemical setting can enable bond constructions that would be impossible for either of the catalysts alone. An emerging subdomain within the field of multicatalysis are single‐electron transfer processes that are sustained by the synergistic merger of sulfur as well as selenium organocatalysis with photoredox catalysis. From a synthetic viewpoint, such processes bear tremendous value, as they offer new and economic pathways for the concise assembly of complex molecular architectures. Thus, the aim of this Minireview is to highlight recent methodological progress made in this area and to contextualize representative transformations with the mechanistic underpinnings that are enabling these reactions.
