Title: Breaking the paradigm: Record quindecim charged magnetic ionic liquids

A family of bis(trifluoromethanesulfonyl)amide-based ionic liquids of composition [RE 5(C 2H 5-C 3H 3N 2-CH 2COO) 16(H 2O) 8](Tf 2N) 15 (RE = Er, Ho, Tm; C 3H 3N 2 ≡ imidazolium moiety) featuring the cationic, record quindecim {15+} charged pentanuclear rare earth (RE)-containing ion [RE 5(C 2H 5-C 3H 3N 2-CH 2COO) 16(H 2O) 8] 15+ has been synthesized and characterized. In addition, due to the presence of rare earth ions, these ionic liquids show a response to magnetic fields with the highest effective magnetic moment observed so far for an ionic liquid and are rare examples of ionic liquids showing luminescence in the near-infrared. As a result, these ionic liquids also were successfully employed in a three-component synthesis of 2-pyrrolo-3'-yloxindole with an extremely low (<0.035 mol%) catalyst loading rate.
