Der Nicht‐Häm‐Eisen( III )‐Komplex [(PaPy 3 )Fe(NO 2 )](ClO 4 ) ( 1 ) überträgt in Acetonitril bei 45–65 °C Sauerstoff auf PPh 3 unter Bildung von OPPh 3 . Das Produkt, [(PaPy 3 )Fe(NO)](ClO 4 ), eine {Fe‐NO} 7 ‐Spezies, bildet in Gegenwart von Disauerstoff rasch wieder den ursprünglichen Komplex 1 , was dem System katalytischen Charakter verleiht (siehe Schema). Durch Bildung einer Oxo‐verbrückten Spezies wird der Sauerstoff‐Transfer abgebrochen. PaPy 3 H= N ‐[ N , N ‐Bis(2‐pyridylmethyl)aminoethyl]‐2‐pyridincarboxamid.
