  FTIR对钴和铁卟啉与CO反应的比较FTIR研究。钴卟啉是否在Ar基体中形成双羰基络合物？

  摘要：

  摘要利用FTIR光谱研究了CO，C18O及其等摩尔混合物在10 K条件下Co（II）（TPP）和Fe（II）TPP（TPP为中四苯基卟啉二价阴离子）与一氧化碳在氩气中的加成反应。 。结果表明，两种金属都可能与CO形成单羰基加合物，但是仅对于卟啉铁才证实形成了双羰基加合物。这些结果驳斥了有关Ar矩阵中存在Co（TPP）（CO）2的早期假设。

  The interaction of carbon monoxide and dioxygen with low-temperature (T = 77 K) sublimates of cob alt(II) meso- tetraphenylporphyrinate (CoTPP) is studied by IR spectroscopy using is otopically labeled compounds ((CO)-C-13 and O-18(2)). The obtained data confirm the coordination of CO and O-2 with the formation of axial complexes CoTPP L (L = O-2, CO) and the mixed complex O-2 CoTPP CO. The heating of the complex containing CO and O-2 to 150 K leads to the appearance of lines in the IR spectrum corresponding to valence asymmetric (v(as)OCO) and degenerated deformation (delta OCO) vibrations of carbon dioxide. This is evidence for the oxidation of CO. The evacuation of CO2 at a higher, but still low, temperature and the addition of a new portion of CO and O-2 mixture lead to the formation of new portions of CO2. This demonstrates the catalytic character of the process. Only low-temperature sublimates have catalytic properties. Sublimates of CoTPP obtained on the surface at room or higher temperature demonstrate neither catalytic activity nor the ability to coordinate any amount of CO and O-2 sufficient for the detection by spectroscopy.
