Abstract: | Europium bis(trifluoromethanesulfonyl)amide, Eu(NTf2)3 (Tf=SO2CF3), was found to catalyze efficiently the electrophilic substitution reactions of indoles with aldehydes or ketones to afford the corresponding bis(indol-3-yl)methanes in high yields at room temperature. Eu(NTf2)3 could be reused. |

Keywords: | bis(indol-3-yl)methane indole aldehyde ketone Eu(NTf2)3 |
