摘要：

Reactions of (porphinato)iron(IIl) complexes (porphyrin = H2TPP, H2TTP, and H2OEP) with nitrite ion have been investigated by means of attempted product isolation, UV-visible spectroscopy, solution IR and EPR spectroscopy, and a study of the time dependence of the reaction system. All observations are consistent with an instability of this system that leads not to coordinated nitrite species but rather to the production of iron nitrosyl complexes. These nitrosyl species appear to be formed by single oxygen atom transfer from a coordinated nitrite ion to an uncoordinated nitrite ion. © 1990, American Chemical Society. All rights reserved.
