[摘要]:A new class of task-specific ionic liquids (ILs) which contain septuply positively charged {(Fe3O)-O-III(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. |
