Short summary
·Cl-initiated oxidation of imines was investigated to clarify their atmospheric fate and reaction mechanisms. This study revealed that NH-containing imines mainly yield N-centered radicals, which react with NO to form nitrosamines or with O2 to form cyanide compounds, with pathways strongly dependent on molecular structure of N-centered radicals. This results highlight the role of imines in nitrosamine formation and advance Cl/ONCs chemistry.
