    Abstract: UV-Bestrahlung des neuen [2-Methoxy-α-oxo-phenylmethan]-diphenylphosphins (1) in Benzol führt zur Bildung von Produkten durch α-Spaltung (3) und Photosubstitution (4) sowie zum Phosphinoxid 2. Die Genese von 2 wird durch photoinduzierten 1,2-Sauerstofftransfer aus der Carbonylgruppe auf den Phosphor in 1, neuartige Fragmentierung unter Bildung der Phosphinigsäure 6 und Addition derselben an Aceton erklärt. Die Struktur von 2 wird u. a. durch Röntgenstrukturanalyse belegt.

    UV irradiation of the new [2-methoxy-α-oxo-phenylmethane]-diphenylphosphine (1) in benzene leads to products via α-cleavage (3) and photosubstitution (4) as well as to the phosphine oxide 2. The genesis of 2 is interpreted by photoinduced 1,2-transfer of oxygen from the carbonyl function onto the phosphorous atom in 1, a novel fragmentation under formation of the phosphine oxide 6 and its addition to aceton. The structure of 2 is based on among other methods X-ray analysis.
