摘要：

UV irradiation of nitrosamines in neutral and acidic media has been investigated. In the presence of oxygen (air) in methanol solution dibenzylnitrosamine undergoes photolysis to give N-benzylidenebenzylamine, dibenzylamine and dibenzylammonium nitrate by a radical abstraction mechanism. Under acid conditions nitrosamines eliminate nitroxyl to form alkyldeneimines and these moieties subsequently recombine to produce amidoximes. This latter process has been shown by crossover experiments using isotopically labeled nitrosamines to be an intermolecular reaction. Evidence is presented in favor of a non-stereospecific photoelimination of nitroxyl from nitrosamines which are protonated at the amino N atom. © 1968.
