“…The information on the electronic excited states of diazoketone 1 was obtained using experimental spectra of absorbance (Figure S1a), luminescence (Figure S2), and phosphorescence (Figure S4), observed lifetimes of the excited states (Figure S3 and Table S2), computational studies (Figure S1b and Table S1), and some literature data. − …”

The energies and lifetimes of the excited states (S, S, S, T) of a diazotetrahydrofuranone were determined using experimental and computational methods. It was shown that direction of the diazoketone photochemical transformations without elimination of nitrogen is determined by multiplicity and energy of the excited state, generated by UV irradiation of diazo compound: isomerization to α-ketodiazirine proceeds from the singlet S state, whereas the alternative process of C-H insertion with hydrazone formation occurs through the triplet T state. The most probable excited state that leads to elimination of nitrogen and Wolff rearrangement is one of the highest singlet excited states of diazotetrahydrofuranone.

“…As an air pollutant, DMN is spreading in the atmosphere by factories during the production of dimethylamine, which has been detected at the concentration varying from 0.001 to 0.43 ppb, their frequency is associated with the secondary amine and nitrogen dioxide concentrations in the air (Bretschneider et al, 1973). Dimethylamine hydrochloride treatments with sodium nitrite in the alkaline phase have been reported since 1865 to generate DMN at an acidic pH (Fridman, 1971), there is also significant evidence for the production of N-nitrosamines in the acidic atmosphere prevailing in the stomach of mammals. The nitro reductase containing bacteria can also derive from nitrate enzyme reduction.…”

N-nitroso compounds (NOC) are produced by the acid catalyzed reaction of nitrite with certain nitrogen compounds. The gastrointestinal tract (GI) is the main site for the formation of reactive nitrogen species (RNS). Bacteria present on the GI tract surface reduced the dietary nitrate or nitrite into Nitric oxide NO and other related compounds. The clinical sign of NOC carcinogenicity varies according to species, dose, and route of administration. Humans are exposed to preformed N-nitroso compounds and endogenous NOC via the environmental food chain. Several NOC are potential human carcinogens, including DENA and NDMA, but evidence from population studies is inconsistent.
