The non‐heme iron( III ) complex [(PaPy 3 )Fe(NO 2 )](ClO 4 ) ( 1 ) transfers oxygen in the temperature range 45–65 °C to PPh 3 to afford OPPh 3 in MeCN. The product, [(PaPy 3 )Fe(NO)](ClO 4 ), a {Fe‐NO} 7 species, reverts rapidly back to 1 in the presence of dioxygen, thus making the system catalytic (see scheme). Formation of an oxo‐bridged species terminates the oxo‐transfer process (PaPy 3 H= N ‐[ N , N ‐bis(2‐pyridylmethyl)aminoethyl]‐2‐pyridinecarboxamide).
