Fig. 5. Scope of the bifunctional chalcogenonitriles in photochemical chemodivergent reaction.

^aReaction conditions A: 1 (0.4 mmol), 2 (0.2 mmol), PTH2 (5 mol%), and degassed toluene (2 mL) under argon with irradiation of LEDs (λ_max = 390 nm) with 100% intensity at 30–35 °C for 30 mins. ^bReaction conditions B: 1 (0.4 mmol), 2 (0.2 mmol), PTH4 (5 mol%), and degassed toluene (2 mL) under argon with irradiation of LEDs (λ_max = 390 nm) with 100% intensity at 30–35 °C for 24 h. ^cisolated yield. ^dfac-Ir(ppy)₃ (1 mol%) as catalyst. ^eafter completion of photoredox reaction, AlCl₃ (1 equiv.) was added at 0 ^oC for 1 h.
