WebThe reaction was carried out using 2–6% photocatalyst and 50% 2,4,6-triisopropylbenzenethiol (TRIP thiol) in toluene under blue light irradiation for 12 h at room temperature. In the presence of Ir[dF(Me)ppy] 2 (dtbbpy)PF 6, the intramolecular hydroamination reaction produced the desired amination product 4a in 53% isolated yield … WebApr 12, 2024 · TRIP thiol was then added from a 0.1 mmol/mL stock solution in methanol (10 mol %) followed by the methanol solvent (0.1 mmol epoxide/mL methanol). This solution was sparged with a nitrogen balloon for 10 min, and the vial was twice sealed with parafilm. The mixture was then stirred and irradiated with a 427 nm LED (Kessil).
