A monoalkoxy phenyl group as a dummy ligand on indolyl(aryl)iodonium imides, which is related to the N–I bonding hypervalent iodine(III) compound, for the copper-catalyzed indole-selective C–N coupling reaction was designed to provide 3-bissulfonimido-indole derivatives in high yields. In particular, the use of indolyl(2-butoxylphenyl)iodonium bissulfonimides indicated the high indole selectivity.
