Description
Summary:The Cover Feature shows the photoelectrochemical activation of C−H bonds with mesoporous SnO2 electrodes sensitized with a quinacridone dye (pigment violet 19, used in paints). The key feature of quinacridone is the possibility to operate through a proton‐coupled electron transfer mechanism, generating a nitrogen‐based radical characterized by a bond dissociation free energy (BDFE) of 80.5 kcal mol−1 and capable of hydrogen atom ion from allylic and benzylic C−H bonds.
