Nitrosation under alkaline conditions
Abstract
Both gaseous N2O3 and N2O4, but not NO, are shown to effect the nitrosation of primary and secondary amines in neutral and alkaline aqueous solutions; the reaction rates are rapid, insensitive to amine basicity and are not inhibited by HO–, which is consistent with radical pathways involving NO2 and NO, and therefore carcinogenic N-nitrosamines may form under a much wider range of experimental conditions than hitherto suspected.
