The catalytic oxidation of 2,4,6-tri-tert-butylphenol and 2,4,6-tri-tert-butylaniline with molecular oxygen and tert-butylhydroperoxide was investigated using biomimetic Mn-, Fe- and Co-complexes as catalysts. The catalytic activity and product distribution were determined and compared with those observed in the reactions of the well-known Co(salen) complex.

9,10-Dicyanoanthracene (DCA)-sensitized photooxidation reactions of hindered phenols and catechols (I) proceed via the initial electron transfer from 1 to **1DCA. 4-Hydroperoxy-2,5-cyclohexadien-1-ones and 4-hydroxy-2,5-cyclohexadien-1-ones are obtained from 2,4,6-trialkyl-substituted phenols, and an o-benzoquinone and furanone derivatives are afforded from 3,5-di-t-butylcatechol.
OXYGENATION OF 2,6-DI-t-BUTYLPHENOLS WITH SUPEROXO Co(lll) COMPLEXES
Nishinaga, A.,Tomita, H.,Matsuura, T.
, p. 2833 - 2836 (2007/10/02)
Superoxo Co(lll) complexes, *3 where X= Et3N(+) and (Ph3P)2N(+), mediate the dioxygen incorporation into 2,6-di-t-butylphenols (1) with the same regioselectivity as that in the base-catalyzed oxygenation of 1.The superoxo species acts as a base but is not incorporated into the substrate.
