Vor über 40 Jahren wurde die Blockierung der N5‐Position von Flavin durch Wasserstoff vorhergesagt, jetzt wurde dafür in der Untersuchung eines Peroxyflavinium‐Intermediats erstmals der direkte Nachweis erbracht. In ihrem Forschungsartikel auf S. 15558 zeigen J. Roithová et al., wie Massenspektrometrie und Ionenspektroskopie genutzt werden können, um Intermediate mit einer Lebensdauer von unter 1...
Flavin‐based catalysts are photoactive in the visible range which makes them useful in biology and chemistry. Herein, we present electrospray‐ionization mass‐spectrometry detection of short‐lived intermediates in photooxidation of toluene catalysed by flavinium ions (Fl+). Previous studies have shown that photoexcited flavins react with aromates by proton‐coupled electron transfer (PCET) on the microsecond...
