Organic photocatalysts (PCs) are emerging as viable and more sustainable tools with respect to metal complexes. Recently, the field of organo-photocatalysis has experienced an explosion in terms of applications, redesign of well-established systems and identification of novel scaffolds. A rational approach to the structural modification of the different PCs is key to accessing unprecedented reactivity,…
The Birch reduction is a powerful synthetic methodology that uses solvated electrons to convert inert arenes to 1,4-cyclohexadienes—valuable intermediates for building molecular complexity. Birch reductions traditionally employ alkali metals dissolved in ammonia to produce a solvated electrons for the reduction of unactivated arenes such as benzene (Ered < -3.42 V vs. SCE). Photoredox catalysts have…

A long excited state lifetime is a desirable quality of photocatalysts because it enables a higher probability of energy or electron transfer from the photocatalyst to a substrate. However, achieving a long lifetime in organic (metal-free) catalysts is challenged by competing rapid nonradiative relaxation from excited states and relatively slow intersystem crossing into long-lived states…
