Substituted phenols are oxidized by phenyliodonium diacetate in methanol to yield either cyclohexa-2,4- or the isomeric 2,5-dienones depending upon the structure of the phenol. Annulation of these oxidation products with the anion of 3-cyanophthalide affords access to a range of anthraquinones not previously accessible by this route.

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.

A one-pot synthesis of anilines and nitrosobenzenes from phenols has been developed using an ipso-oxidative aromatic substitution (iSOAr) process. The products are obtained in good yields under mild and metal-free conditions. The leaving group effect on reactions that proceed through mixed quionone monoketals has also been investigated and a predictive model has been established.
