PPTNOs are structurally related to flavins and share their reactivity to a certain degree. This similarity was shown in isomerization and oxidation reactions. PPTNOs are very potent photocatalysts that even enable oxidation reactions of mono substituted amines. The potency of the PPTNOS was revealed in a photocatalytic hydroamination using stilbenes and mono substituted amines. Subsequently a photocatalytic trifluoromethylation was investigated to further show the applicability of these photocatalysts.
