Abstract

We report a new synthesis of 3-nitroveratrole, based on the directed lithiation of veratrole, and photochemical substitutions of both 3-nitroveratrole and o-nitroanisole with several nucleophiles. Both aromatic substrates undergo photocyanation meta to the nitro group. With hydroxide ion, 3-nitroveratrole reacts meta to the nitro group, but 2-nitroanisole undergoes replacement of either substituent, the proportion of reaction at each site ...
