    Description / Table of Contents: Zusammenfassung Photolyse der 3-Phenylpropiophenone1 a–d in Gegenwart von 2,4,6-Triphenyl-pyrylium-tetrafluoroborat (TPT) ergeben die entsprechenden α,β-ungesättigten Ketone2 a–c und1 d (aus1 c), neben Acetophenon (3), Benzophenon (4), Benzoesäure (5) und Benzaldehyd (6), vermutlich durch Fragmentierung des Radikal-Kations1 + ·, das mittels Übertragung eines Elektrons von1 zuTPT im angeregten Zustand erzeugt wird.
    Notes: Summary Photolysis of 3-phenylpropiophenones1 a–d in the presence of 2,4,6-triphenylpyrylium tetrafluoroborate (TPT) yields the corresponding α,β-unsaturated ketones2 a–c and1 d (from1 c), together with acetophenone (3), benzophenone (4), benzoic acid (5) and benzaldehyde (6), presumably by fragmentations of the radical cation1 + ·, generated via a single electron transfer process from1 to the excitedTPT.
