Abstract

A new class of task-specific ionic liquids (ILs) which contain septuply positively charged {Fe(3)(III)O(RCOO)(6)L(3)}(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-3'-yloxindole or the condensation of indoles with various aldehydes.
