✦ Synopsis


Structures of Oxidation Products of 4,6-Di-tert-butylpyrogallol.

-The oxidation of title compound (I) with 1,4-benzoquinone affords the dimeric product (II) derived from a regio-and stereospecific dimerization of intermediate 1,2-benzoquinone (III), the expected oxidation product, according to a [4+2] cycloaddition mechanism. The oxidation of (I) with potassium ferricyanide affords the dimer (IV) via a radical recombination mechanism. The structures of the oxidation products are confirmed by X-ray diffraction analyses. (Yields are given in g). -(SHIF, A.
