Saritha, Rajendhiran published the artcileMetal-free, regioselective, visible light activation of 4CzIPN for the arylation of 2H-indazole derivatives, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is arylated indazole regioselective preparation; indazole aniline arylation tetrakiscarbazolyl dicyanobenzene photocatalyst.
Highly regioselective organo photocatalysis of 4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene) for the arylation of 2H-indazole was demonstrated to obtain arylated indazole derivatives I [R1 = H, Cl, Br, CN; R2 = H, Cl; R3 = H, F, MeO, etc.; R4 = Ph, 4-FC6h4, Bn, etc.; R5 = H, MeO]. The present synthetic route provided a highly safe and easily accessible aniline precursor as an arylation reagent. The photoactivated 4CzIPN organocatalyst was found to be more efficient for single electron transfer without any organic base for the radical reaction. The carbazole-based photocatalyst (4CzIPN) with wide redox potential was stable and recyclable for further reaction transformations. Many indazole and aniline derivatives were used in the reaction and provided the arylated indazole derivatives in good to excellent yield.
