a The mechanism for electrooxidative C-H/N-H cross-coupling between 1a and 2a deduced by the identified intermediates. b–d The positive-ion-mode mass spectrum (b), The extracted ion chromatograms (EICs) of internal standard (IS) (m/z 146.1176) and product 3aa′ (m/z 318.1194) (c) and time-dependent relative intensity ratio of 3aa′ to IS (d) obtained by DEC-FMR-MS for the high-throughput testing of the electrooxidative radical-radical cross-coupling between DMA and PTA in dual electrolysis mode. e Comparison of the relative ion signal intensity ratio of 3aa′ to IS obtained by online reaction in the DEC-FMR-MS platform and conventional batch reaction. The error bars in (e) represent the standard deviations of three replicates.
