Photoredox Catalysis: The Need to Elucidate the Photochemical Mechanism.

Marianna Marchini¹, Giacomo Bergamini¹, Pier Giorgio Cozzi¹, Paola Ceroni¹, Vincenzo Balzani¹.

Abstract

The photocatalytic mechanism reported in a recent Communication to produce the radical anion of pyrenes postulates a highly endergonic electron transfer process. An analysis of the thermodynamics is reported together with the proposal of an alternative thermodynamically feasible mechanism.
