Summary

The reaction of nitrosyl iron tetraphenylporphyrin (NO-Fe(TPP)) with nitric oxide (NO) gas forms a transient N--N-coupled adduct. This intermediate is key to understanding NO-Fe(TPP) transformations and potential N2O production.

Area of Science:

  • Inorganic chemistry
  • Organometallic chemistry
  • Reaction mechanisms

Background:

  • Nitrosyl iron porphyrins (NO-Fe(TPP)) are important in coordination chemistry.
  • Understanding the reaction pathways of NO-Fe(TPP) with nitric oxide (NO) is crucial for catalytic applications.

Purpose of the Study:

  • To elucidate the reaction mechanism of NO-Fe(TPP) with low pressures of NO gas.
  • To identify key intermediates and their roles in the transformation processes.
  • To investigate the potential for catalytic production of nitrous oxide (N2O).

Main Methods:

  • Spectroscopic analysis, including IR spectroscopy, was used to identify transient intermediates.
  • Isotope labeling experiments (14N/15N) were employed to track atom transfer and coupling.

  • Kinetic studies and mechanistic proposals were developed based on experimental observations.

    • Main Results:

    • A transient N--N-coupled (NO)2 adduct intermediate was identified.
    • The formation of NO(NO2)Fe(TPP) was observed, suggesting a pathway involving free NO2.
    • Catalytic production of N2O was achieved by using a competitive oxygen atom acceptor (PPh3).
    • Cross-labeling experiments confirmed the equivalence of oxygen atoms in the intermediate.
    • IR spectroscopy confirmed transient, isotope-sensitive bands indicative of the intermediate.

    Conclusions:

    • The reaction proceeds through a distinct N--N-coupled adduct intermediate.
    • A proposed mechanism explains the formation of nitrite and N2O.
    • Oxygen atom transfer from the intermediate is efficient and involves equivalent oxygen atoms.
    • The study provides insights into the reactivity of NO-Fe(TPP) and potential catalytic cycles.
