Abstract

Novel supported task-specific ionic liquids have been developed for the first time via the ionic-pair coupling of imidazolium cation of the modified polystyrene support with l-proline. The materials have shown an efficient metal scavenging ability (eg, CuI, Pd (OAc) 2, Pd0, and IrCl3) without the aid of a nonimmobilized ionic liquid, which relies on the highly synergistic effect of the coordination with the nitrogen atom and the COO-group of the l- ...
