P-quinols and p-quinol Ethers from 2,4,6-trialkylphenols

, p. 208 - 210 (2010)
The oxidation of 2,4,6-trialkylphenols with lead(IV) oxide and 70% perchloric acid in water-acetone or in alcohols gives p-quinols or p-quinol ethers, respectively. Some nonmetallic oxidants serve the same purpose. Georg Thieme Verlag Stuttgart.
