Conclusions

  1. 1.

    It has been shown by means of ESR that PPh3 is implanted in the coordination sphere of iron, chromium, and molybdenum in the photochemical interaction of the carbonyls of these metals with CCl4, in the presence of PPh3.

  2. 2.

    The replacement of the CO groups in the metal carbonyls by PPh3 leads to increases in the yields and activity of the intermediate metal-containing species that are responsible for the stage of organic radical generation.

  3. 3.

    In the photochemical decomposition of substituted carbonyls of chromium, molybdenum, and tungsten, it is mainly the metal-CO bond that is ruptured, not the metal-PPh3 bond.
