[Cp*IrCl₂]₂ Catalyzed Formation of 2,2′-Biindoles from 2-Ethynylanilines

Abstract

[Cp*IrCl2]2 catalyzes the cyclization of 2-ethynylanilines to 2,2'-biindoles via intramolecular hydroamination. A reaction pathway has been proposed on the basis of deuterium labeling experiments and computational studies.
