Although photoredox catalysis is complex from a mechanistic point of view, it is also often surprisingly efficient. In fact, the quantum efficiency of a puzzlingly large portion of photoredox reactions exceeds 100% (i.e., the measured quantum yields (QYs)

Photoredox Catalysis Is On A Roll
Chemical & Engineering News Archive, 2015The practice of using light to drive catalytic reactions is hotter than ever. The field of photoredox catalysis may trace its origins back to the late 1970s, but its popularity has grown considerably over the past five years. Most recently, David W. C.

Generating carbyne equivalents with photoredox catalysis
Nature, 2018Carbon has the unique ability to bind four atoms and form stable tetravalent structures that are prevalent in nature. The lack of one or two valences leads to a set of species-carbocations, carbanions, radicals and carbenes-that is fundamental to our understanding of chemical reactivity.

Metal‐Free Carbonylations by Photoredox Catalysis
Angewandte Chemie International Edition, 2014AbstractThe synthesis of benzoates from aryl electrophiles and carbon monoxide is a prime example of a transition‐metal‐catalyzed carbonylation reaction which is widely applied in research and industrial processes. Such reactions proceed in the presence of Pd or Ni catalysts, suitable ligands, and stoichiometric bases.

Photoredox Catalysis for Organic Syntheses
Advanced Synthesis & Catalysis, 2013AbstractCurrent examples of photoredox catalytic processes for CO, CN, CHal and CC bond formation are described with emphasis on the basic mechanistic scenarios. The focus is on the special aspects of photochemical redox catalysis especially on the electron transfer energetics, the use of electron transfer (ET) sensitizers and mediators as well as ...
