L. Cheng et al., The first unambiguous determination of a nitrosyl-to-nitrite conversion inan iron nitrosyl porphyrin, CHEM COMMUN, (23), 2000, pp. 2301-2302
The picket fence porphyrin complex [Fe(tpivpp)(NO)] undergoes complete conv
ersion to the isolable N-bound nitrite derivative [Fe(tpivpp)(NO2)(py)] in
air in the presence of pyridine: reconversion to the starting nitrosyl comp
lex is achieved using triphenylphosphine as reductant.
