A The monitoring in situ of ethylene release by crude 1H NMR using acetone-d6 as the solvent in the NMR tube. B Competitive experiments. C 1, 5-HAT process. D The radical trapping experiment by TEMPO. E Radical self-cross-coupling in the absence of additional alkenes. F Comparison with the similarly designed CF3-reagent. Standard condition: performed at 0.1 mmol scale in methyl tert-butyl ether (MTBE, 0.1 M) under 390 nm LEDs for 1 h, using thioxanthone (10 mol%). See Supplementary Sections 7 for experimental details.
