A specific oxygenation of phenols to ortho-quinones can be effected by a combination of the transition metal complexes Ti(OiPr)4, VO(acac)2, Zr(acac)4, Zr(OnPr)4 and tert-butylhydroperoxide (TBHP) or * Py * HMPT.Naphthols, anthracenols, phenanthrols and donor substituted mononuclear phenols are readily converted into the corresponding 1,2-quinones.Unhindered ortho-naphthoquinones can yield binaphthyls with unreacted starting material by Michael addition. - Key Words: ortho-Quinones / tert-Butyl hydroperoxide / Phenols, oxygenation
