✦ Synopsis

The photochemical transposition of alkylbenzenes through their valence tautomers has recently received much attention:

We wish to report a new type of photochemical trensposition of hindered 2,6-di-t-butylphenols.

The oxygenation of 4-(N-arylmethyleneamino)-2,6-di-t-butylphenols with Co(Salpr), a five coordinate Co(I1) Schiff base complex, in CH2C12 results in the regioselective hydroperoxylation at the imino carbon to give N-(1-aryl-1-hydroperoxymethyl)-3,5-di-tbutyl-R-benzoquinone mnoimines, which give excl

Radical pairs are formed by photolysis of single crystals of 2,6-di-tert-butyl-4-methylphenol (ionol) (1) or 2,6-di-tert-butylphenol (2 ), doped by several different molecules, and investigated by the EPR method. A possible two-hydrogen-atom transfer is discussed as the photochemical act.
