Oxidation of bisbenzenechromium(0) by stable phenoxyl radical

  • 18 Accesses

Conclusions

  1. 1.

    (C6H6)2Cr(0) is oxidized by the stable 2,4,6-tri-tert-butylphenoxyl radical to the saltlike bisbenzenechromium 2,4,6-tri-tert-butylphenolate.

  2. 2.

    It was shown that the phenolate can undergo dissociative sublimation.

  3. 3.

    The phenolate undergoes thermal decomposition by the disproportionation mechanism, in which the initial step is dissociation of the phenolate to (C6H6)2Cr(O) and the phenoxyl radical.
