Abstract:Abstract. The atmospheric chemistry of organic nitrogen compounds
(ONCs) is of great importance for understanding the formation of
carcinogenic nitrosamines, and ONC oxidation products might influence
atmospheric aerosol particle formation and growth. Indole is a
polyfunctional heterocyclic secondary amine with a global emission quantity
almost equivalent to that of trimethylamine, the amine with the highest
atmospheric emission. However, the atmospheric chemistry of indole remains
unclear. Herein, the reactio… Show more

“…Recently, Xue et al also found that both ˙Cl addition and hydrogen-abstraction from N-sites were feasible for the reaction of indole with ˙Cl, while ˙OH addition was the dominant pathway in the case of the ˙OH reaction. 122 Obviously, the reaction of ˙Cl with amines is quite different from that of ˙OH. Hence, to assess the fate of atmospheric amines more accurately, it is necessary to consider both the atmospheric concentrations of ˙Cl and ˙OH and their initial reaction steps with atmospheric amines.…”

“…Their group further found that the delocalized character of N-center radicals formed by indole is the reason why they wouldn't further form nitrosamine. 122 It is evident that the potential, efficiency and stability of N-center radical forming nitrosamines are highly dependent on the structure and the functional groups of parent amines.…”
