N-Nitration of 4-chloro-5-substituted-pyridazin-3-one with copper nitrate trihydrate in acetic anhydride gave the corresponding 4-chloro-2-nitro-5-substituted-pyridazin-3-one. 4-Chloro-5-alkoxy-2-nitropyridazin-3-ones such as 5-methoxy (2b) and 5-ethoxy (2d) derivatives showed excellent nitro group transfer potentiality. N-Nitration of some secondary amines with 2b gave the corresponding N-nitramines under mild neutral condition in good yields.

Electrochemical oxidation of N-nitrosamines (1) derived from symmetrical dialkylamines was investigated in acetonitrile in the presence of dissolved oxygen.On cyclic voltammetry at ambient temperature, 1 showed two or three irreversible anodic peaks, depending upon the structure.Macroscale electrolysis, either controlled potential or constant current, of 1 which showed three voltammetric peaks gave the corresponding nitramine (2) and N-alkyl-N-(2-oxoalkyl)nitrosamine (3) as the main products.In the case of 1 which showed two voltammetric peaks, however, the side chain oxidized nitrosamine 3 was not obtained.It is suggested that the oxygen atom incorporated in the products 2 and 3 originated from dioxygen dissolved in the medium, and that the numbers of electrons required for the formation of 2 and 3 are one and two, respectively.A possible reaction sequence, which involves the reactions of the radical cation (4) derived from 1 and a radical formed by intramolecular rearrangement of 4 with dioxygen, is proposed.Keywords---N-nitrosodialkylamine; N-nitramine; N-alkyl-N-(2-oxoalkyl)nitrosamine; electrochemical oxidation; cyclic voltammetry; controlled potential electrolysis; constant current electrolysis

Controlled potential electrolysis, based on the results of cyclic voltammetry, of simple dialkylnitrosamines such as N-nitrosodibutylamine and N-nitrosodicyclohexylamine in acetonitrile at a glassy carbon electrode resulted in the formation of the corresponding nitramines as the major products together with β-ketonitrosamines in which the carbonyl group is on the same side of the nitroso-oxigen atom.With N-nitrosopiperidine, one derived from a cyclic amine, N-nitropiperidine was formed similarly but the β-oxidized nitrosamine was not detected in the electrolysis solution.In deoxygenated acetonitrile, neither the nitramines nor the β-ketonitrosamines were obtained from the electrolysis. - Keywords: N-nitrosamines; N-nitramines; β-ketonitrosamines; anodic oxidation; cyclic voltammetry; controlled potential electrolysis
