In situ electron paramagnetic resonance (EPR) monitoring of the photocatalytic halogen atom transfer (XAT) reaction with organic amines has provided insights into the dynamic transformations of intermediates, including catalyst intermediate states, amine alkyl radicals, and the dehalogenation of halogenated hydrocarbons to form carbon-centered radicals. This approach facilitated the photocatalytic single-linear state oxygen-promoted halogen atom transfer quinoxalinone alkylation reaction.

Key words: electron paramagnetic resonance (EPR), reaction intermediates, halogen atom transfer (XAT), photocatalyst, alkylation
