experimental part, p. 1728 - 1733 (2009/02/06)
Investigation of the catalyzed reaction of 2,6-di-tert-butylphenol with ethanol, ethylene glycol, oligomeric glycols, and paraldehyde in a strongly basic medium permitted to develop a technologically suitable procedure for manufacture of 2,6-di-tert-4-ethyl-butylphenol, used in the synthesis of Antioxidant-425.
Novel Reduction of 2,6-Di-t-butyl-p-quinols with Sodium Borohydride

Reduction of 2,6-di-t-butyl-p-quinols with NaBH4 results unexpectedly in the regio- and stereoselective formation of the corresponding dihydro-p-quinols.The novel reduction occurs via a quinoxyborohydride anion intermediate, which regulates the stereochemistry of the 4- and 6-positions in the products.Aromatization of the products is blocked by the t-butyl groups.
Peroxy Esters. 9. Base- and Radical-Induced Decomposition of 1-Alkyl-3,5-di-tert-butyl-4-oxo-2,5-cyclohexadienyl 3,5-Di-tert-butyl-4-hydroxyperbenzoates

The title peroxy esters 1, when deprotonated with t-BuOK in DMF to the corresponding phenolate anions, decompose even at -78 deg C to give compounds 2-10.These compounds result undoubtedly from homolysis of the peroxy bond in 1, indicating that the generation of a carbanion at the α-position of the acyl group in peroxy esters (via resonance in the present case) induces ready homolysis of the peroxy bond.The oxidation of 1 with one-electron oxidizing agents gives rise to the corresponding phenoxy radicals, which also induce homolysis of the peroxy bond.
