Iron-catalyzed oxidative homo-coupling of indoles via C–H cleavage

Iron-catalyzed oxidative homo-coupling of indoles via C–H cleavage

The authors, Tianmin Niu and Yuhong Zhang from Zhejiang University, peoples republic of China reported a cheap Fe catalysed Oxidativecoupling of N-H indoles. Its a new method for the homo-coupling of indoles has been developed by the use of FeCl3 as catalyst and molecular oxygen as the only oxidant. The protocol provides a practical and straightforward approach toward 3,3′-biindolyls.
