Fig. 4. Expanding the pool of radical precursors. Reactions performed using 1 (0.2 mmol), 4 (0.6 mmol), Cs₂CO₃ (2 equiv.) in 1 mL of CH₃CN under irradiation by a Kessil lamp (λ_max = 390 nm, irradiance = 100 mW cm⁻²). Yields of the isolated products 5 are reported below each entry; results are averaged from two runs.
