Abstract
A monoalkoxy phenyl group as a dummy ligand on indolyl(aryl)iodonium imides enables a copper-catalyzed indole-selective C-N coupling reaction to provide 3-bissulfonimido-indole derivatives in high yields. A one-pot synthesis of 3-bissulfonimido-indole derivatives directly from indoles, bissulfonimides, and (diacetoxyiodo)-2-butoxybenzene is also reported.
