A simple and efficient one-pot synthesis of p-quinols and their ethers occurs over tungstate-exchanged layered double hydroxides (WO4 2--LDHs), which catalyze the bromide-assisted oxidation of substituted phenols to the corresponding 4-alkoxy- and 4-hydroxycyclohexa-2,5- dienones in high yields (see scheme).
Oxidation with hypervalent iodine reagents. Part II: Novel cyclohexadienones as precursors for the synthesis of anthraquinones

The oxidation of substituted phenols with phenyliodonium diacetate in methanol was found to afford 2,4-cyclohexadienones, 2,5-cyclohexadienones or mixtures of isomers, depending on the substrate being oxidized. Annulation of these cyclohexadienones with the anion of 3-cyanophthalide afforded anthraquinones in high yields.
Oxidations Of Substituted Phenols With Hypervalent Iodine : Applications To The Phthalide Annulation Route To Anthraquinones
Mitchell, Anthony S.,Russell, Richard A.
, p. 545 - 548 (2007/10/02)
Substituted phenols are oxidized by phenyliodonium diacetate in methanol to yield either cyclohexa-2,4-dienones or the isomeric 2,5-dienones depending upon the structure of the phenol.Annulation of these oxidation products with the anion of 3-cyanophthali
