A single-electron transfer mediated modular indole formation reaction from a 2-iodoaniline derivative and a ketone has been developed. This transition-metal-free reaction shows a broad substrate scope and unconventional regioselectivity trends. Moreover, important functional groups for further transformation are tolerated under the reaction conditions. Density functional theory studies reveal that the reaction proceeds by metal coordination, which converts a disfavored 5-endo-trig cyclization to an accessible 7-endo-trig process.

A general and selective method has been achieved to synthesize 2,3'-biindolyls and 2,2'-indolylpyrroles through an acid catalyzed reaction of 3-bromoindoles with indoles or pyrroles.I.R., (1)H-NMR, (13)C-NMR and MS data of the dimers are also reported.
