While photochemical transformations with sunlight almostexclusively utilize the UV-vis part of the solar spectrum, the majority ofthe photons emitted by the sun have frequencies in the near-infraredregion. Phthalocyanines show high structural similarity to the naturallyoccurring light-harvesting porphyrins, chlorins, and mainly bacteriochlor-ins and are also known for being efficient and affordable near-infrared lightabsorbers as well as triplet sensitizers for the production of singlet oxygen.Although having been neglected for a long time in synthetic organicchemistry due to their low solubility and high tendency towardaggregation, their unique photophysical properties and chemical robust-ness make phthalocyanines attractive photocatalysts for the application innear-infrared-light-driven synthesis strategies. Herein, we report a cheap,simple, and efficient photocatalytic protocol, which is easily scalable undercontinuous-flow conditions. Various phthalocyanines were studied as near-infrared photosensitizers in oxidative cyanations oftertiary amines to generate alpha-aminonitriles, a synthetically versatile compound class (AU) | |
