✦ Synopsis

3-(2%-Nitrovinyl)indole reacted with indole and 1-and 2-alkylindoles on TLC-grade silica gel under microwave irradiation to furnish in 7-10 min bis(indolyl)nitroethanes in high yields (70-86%). The same products were also obtained in 69-84% yields without microwave irradiation, but the reactions required 8-14 h for completion. Skatole was inert under both sets of conditions.
