Phase-transfer Catalysis under Reductive Conditions: Hydroquinone Dialkyl Ethers from Quinones Hydroquinone ethers with alternant and nonalternant topology are prepared in one-pot reactions from the corresponding quinones by using sodium dithionite, sodium hydroxide, and alkylating reagents under phase-transfer conditions (Adogen 464). The use of allyl bromide leads to O- and C-allylation.
