Resumo4-Nitroanisole photoreacts with n-hexylamine and ethyl glycinate giving rise to regioselective methoxy and nitro group photosubstitutions respectively. Mechanistic evidences indicate the last is produced through a SN23Ar* reaction whereas the first arises from a radical ion pair via electron transfer from the amine to a 4-nitroanisole triplet excited state.
