Phenolic oxidation with (diacetoxyiodo) benzene
A Pelter, S Elgendy - Tetrahedron letters, 1988 - Elsevier
Abstract (Diacetoxyiodo) benzene oxidises quinols and extended quinols to the
corresponding quinones smoothly and in high yield. Excess of the reagent in methanol with
monohydric phenols directly yields p-quinone ketals, also in good yields. 4-Alkyl and 4-
alkoxyphenols give the corresponding 4-alkyl-4-methoxycyclohexadienones and 4-alkoxy-4-
methoxycyclohexadienones.
