Abstract
Hydroxybenzenes can be produced in high yield through a one-step reaction by subjecting (a) an .alpha.,.alpha.-dialkyl-.alpha.-hydroxymethyl group containing benzene and/or (b) a benzene containing both .alpha.,.alpha.-dialkyl-.alpha.-hydroxymethyl and .alpha.,.alpha.-dialkyl-.alpha.-hydroperoxymethyl groups to reaction in the presence of a nitrile, an acid and hydrogen peroxide. In a preferred mode, the reaction system further contains (c) an .alpha.,.alpha.-dialkyl-.alpha.-hydroperoxymethyl group containing benzene.
