Abstract

Abstract : A family of cationic, record quindecim {15+} charged [(Er, Ho, Tm)5 (C2 H5 -Im-CH2 COO)16 (H2 O)8 ](Tf2 N)15 magnetic ionic liquids has been synthesized and fully characterized. Abstract : A family of bis(trifluoromethanesulfonyl)amide-based ionic liquids of composition [RE5 (C2 H5 -C3 H3 N2 -CH2 COO)16 (H2 O)8 ](Tf2 N)15 (RE = Er, Ho, Tm; C3 H3 N2 ≡ imidazolium moiety) featuring the cationic, record quindecim {15+} charged pentanuclear rare earth (RE)-containing ion [RE5 (C2 H5 -C3 H3 N2 -CH2 COO)16 (H2 O)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. 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.
