Photochemische Oxygenierung von 2,4,6-Tri-tert.-butyl-λ3-phosphorin und 2,4,6-Tri-tert.-butyl-1,1-dimethoxy-λ5-phosphorin

Abstract: Oxygenierungen von Heterocyclen mit durch Photosensibilisierung erzeugtem Singlettsauerstoa" fanden in der letzten Zeit grol3es Interesse [']. Wir beobachteten eine ( a ) , R = H (b), R = CH, 14) 13) + x /O" ( a ) , R = H (b), R = CH, 14)13) + r + + aufgrund der Elementaranalyse sowie des UV-, IR-, NMR-und Massenspektrums die Konstitution (4). Wir nehmen den durch die Formeln (1) bis (4) dargelegten Reaktionsverlauf an. Das Primarprodukt (2) wurde nicht in Substanz gefal3t, wie dies auch bei anderen Oxygenieru… Show more

“…The reaction of singlet oxygen with phosphorin 9 results in the unstable endoperoxide 10, which further rearranges to nonperoxy derivatives. 32 The reaction of pentaphenylphosphine (11) with fert-butyl hydroper-Ph5P + CMe3OOH -Ph4POOCMe3 11 12 oxide gives the peroxy derivative 12 which likewise cannot be isolated. 33 Similarly, the reaction of pentaphenylphosphine (11) with hydroperoxides of silicon (13) and germanium (15) affords the phosphorus per-Ph5P + (CH3)3SiOOH -Ph4POOSiC(CH3)3 11 13 14…”
