J. E. Dunbar M.W. Lansford R. L. Pedrotti F. M. Scheidt F. G. H. Lee E. C. Smith G. R. Yohe 1959 The acidic compound C14H22O3, previously reported without assignment of structure as an oxidation product of 2,6-di-tert-butyl-4-methylphenol, is now believed to be DL-trans-5,6-di-tert-butyl-2-hydroxy-1,4-diketo-2-cyclohexene (I). Chemical properties are described and infrared spectra are presented in support of this structure. This structure is of interest in relation to the problem of the existence of o-di-tert-alkylbenzene derivatives. The relatively easy racemization of optically active I suggests that its completely enolized form, 5,6-di-tert-butyl-1,2,4-trihydroxybenzene, is capable of transitory existence. application/pdf 10.1021/jo01091a023 en American Chemical Society Oxidation of 2,6-di-tert-butyl-4-methylphenol.
