Under Indium catalysis, diverse alkylindoles were successfully prepared with a flexible combination of indoles and alkynes in the presence of hydrosilanes. In addition to the hydrosilane, carbon nucleophiles are also available. This new method generates alkylindoles in yields over 70% with a broad scope of functional group compatibility.

Gold-catalyzed hydroarylation of unactivated alkynes with indoles have previously been reported to proceed with double indole addition to produce symmetrical bis(indolyl)methanes (BIMs). We demonstrate for the first time that the selectivity of the gold-catalyzed reaction can be fully switched to allow for isolation of the vinylindole products instead. Furthermore, this selective reaction can be utilized to synthesize the more difficult to access unsymmetrical BIMs from readily available starting materials.
