Treatment of the methyl ethers MeOX (X = Me, Ph) with a stoicheiometric amount of bistrifluoromethyl nitroxide [(CF3)2NO·= R·] at room temperature converts them efficiently into their bistrifluoromethylamino-oxymethyl counterparts, RCH2OX; the bis-derivative (RCH2)2O is a minor by-product in the case of dimethyl ether (X = Me). Multiple hydrogen-abstraction increases in importance with diethyl ether
