Bromide-Assisted Oxidation of Substituted Phenols with Hydrogen Peroxide to the Corresponding p-Quinol and p-Quinol Ethers over WO42−-Exchanged Layered Double Hydroxides

A simple and efficient one‐pot synthesis of p‐quinols and their ethers occurs over tungstate‐exchanged layered double hydroxides (WO42−‐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).
