Iron-catalyzed intramolecular cyclotrimerization of triynes to annulated benzenes Saino, Naoko Kogure, Daisuke Kase, Kouki 岡本, 専太郎 Okamoto, Sentaro An iron species derived from FeCl2 or FeCl3 by in situ reduction with zinc powder in the presence of imidazol-2-ylidene or bidentate nitrogen ligand could effectively catalyze intramolecular cycloisomerization of triynes to annulated benzenes. With a 2-iminomethylpyridine ligand, hydrates of FeCl2 and FeCl3 as well as their anhydrous ones could be used.
