A new class of task-specific ionic liquids (ILs) which contain septuply positively charged Fe3IIIO(RCOO)6L3}7+ triangles has been synthesized and structurally characterized. Such metal-containing ILs can be repeatedly used as alternative catalysts in the synthesis of 2-pyrrolo-3â²-yloxindole or the condensation of indoles with various aldehydes.

An InCl3-catalyzed one-pot synthesis of 2-pyrrolo-3'-yloxindoles was achieved via three-component reaction of 3-phenacylideneoxindole, beta-keto ester, and ammonium acetate at reflux by a sequential Michael addition followed by Paal-Knorr condensation. (C) 2009 Elsevier Ltd. All rights reserved.
