Reference of fac-Tris(2-phenylpyridine)iridiumIn 2019 ,《Photoredox-catalyzed cascade annulation of N-propargylindoles with sulfonyl chlorides: access to 2-sulfonated 9H-pyrrolo[1,2-a]indoles》 appeared in Organic & Biomolecular Chemistry. The author of the article were Zhang, Pengbo; Shi, Shanshan; Gao, Xia; Han, Shuang; Lin, Jinming; Zhao, Yufen. The article conveys some information:
A photoredox-catalyzed cascade radical reaction of N-propargylindoles I (R1 = H, 6-Me, 7-Me, 5-MeO, 6-F, 6-Cl, 5-Cl; R2 = H, CN, CF3, Me, MeO, F, Cl, Br, I; R3 = H, Me) and sulfonyl chlorides ArS(O)2Cl (Ar = 4-methylphenyl, naphthalen-1-yl, thiophen-2-yl, etc.) to 2-sulfonated 9H-pyrrolo[1,2-a]indoles II (R4 = 7-MeO, 7-Cl, 9-Me, etc.) was described. By the direct use of com. available sulfonyl chlorides as radical precursors, this transformation proceeded smoothly to afford the corresponding products in moderate to good yields under external oxidant-free conditions at room temperature In the experimental materials used by the author, we found fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Reference of fac-Tris(2-phenylpyridine)iridium)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine and pyridine-derived structures are privileged pharmacophores in medicinal chemistry and an essential functionality for organic chemists. As the prototypical π-deficient heterocycle, pyridine illustrates distinctive chemistry as both substrate and reagent. Reference of fac-Tris(2-phenylpyridine)iridium
