A Other different transformations with various substrates by different switchable linkers; B Our strategy applied for CF3SF4 and ArSF4 group. 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 new reagents (1.1 equiv.) and thioxanthone (10 mol%). Isolated yields are reported. Diastereomeric ratios were determined by NMR analysis of crude reaction mixture. a2-Phenyl-1-propene 88 (1.5 equiv.), Ru(DMB)3(PF6)2 (5 mol%), ZnCl2 (0.6 equiv.), TMSN3 (3.0 equiv.), DCM (0.1 M); TMSN3, azidotrimethylsilane. bStyrene 64 (1.0 equiv.), 4CzIPN (5 mol%), dry MeOH (0.02 M), dry DCM (0.1 M); 4CzIPN, 2,4,5,6-Tetra(9-carbazolyl)isophthalonitrile. See Supplementary Sections 2 and 8 for experimental details.
