Nitration of p-dimethoxybenzene by dinitrogen tetroxide in carbon tetrachloride
Abstract
Nitration by dinitrogen tetroxide in carbon tetrachloride appears to proceed by slow nitrosation of the p-dimethoxybenzene followed by rapid oxidation of the nitroso-intermediate. The increase in reaction rate on addition of Lewis acids and the decrease in rate on addition of Lewis bases indicate an ionic mechanism for the nitrosation reaction.
