Magnetic chiral ionic liquids derived from amino acids

Abstract

Novel room temperature magnetic chiral ionic liquids derived from amino acids were synthesized and their magnetic properties as well as chiral discrimination abilities were investigated.

Magnetic microemulsions based on magnetic ionic liquids

“…A rather novel subclass of RTILs are the so-called magnetic RTILs (MRTILs)z, which were first described in 2004 14 and so far only few publications regarding their properties exist. [15][16][17][18][19][20][21][22][23][24][25][26][27] In particular, none in which they have been employed as a main component in self-aggregating systems, despite the fact that, due to their magnetic properties, they are very interesting and promising compounds. In that context it might also be mentioned that ''magnetic surfactants'' have received high attention very recently.…”

Progress in Paramagnetic Ionic Liquids

“…The shortest distance was found for C(2)-H···Cl (3.261 Å), presumably associated with the high acidic character of the 2-hydrogen. Dual functionalities, namely the paramagnetism and chiral discrimination ability, were recently realized by the combination with the chiral protonated L-amino acid methyl esters (1; Scheme 1) (Li et al, 2009 [FeCl 4 ]. Short C-H···Cl contacts are shown by dashed lines.…”

“…Magneto-active metal complex anions, such as Fe III X 4 -(X: Cl, Br) (Yoshida et al, 2005a;Yoshida et al, 2005b;Yoshida & Saito, 2006;Del Sesto et al, 2008;Li et al, 2009), Mn II X 4 2-(X: Cl, Br) (Del Sesto et al, 2008;Pitula & Mudring, 2010), Mn II (Tf 2 N) 3 - (Pitula & Mudring, 2010), Co II X 4 2-(X: Cl, NCS, NCSe, N(CN) 2 ) (Del Sesto et al, 2005;Del Sesto et al, 2008;Peppel et al, 2010), Gd III Cl 6 3- (Del Sesto et al, 2008), and Dy III (SCN) 8-x (H 2 O) x (5-x)-(x: 0-2) (Mallick et al, 2008) ] exhibited long-range antiferromagnetic ordering at 9.5, 4.2, and 12.5 K, respectively (Yoshida et al, 2005b;Yoshida & Saito, 2006). (Yoshida et al, 2005b).…”

Fe- Containing Ionic Liquid Supported on Nanosized MCM-41: An Efficient and Reusable Catalyst in the Synthesis of 2-Aryl Benzimidazole Derivatives

“…The MILs are primarily based on highspin d5 Fe (III) in the form of tetrachloroor tetrabromoferrate(III) with various counter cations. Owing to the high single-ion magnetic moments, these MILs exhibited a strong response to magnetic fields 5 . Since then, much attention has been paid to the design and synthesis of this new class of ILs [6][7][8][9][10] .…”
