Ionic Structures of Nanobased FeCl₃/[C₄mim]Cl Ionic Liquids

Abstract

We synthesized a series of FeCl 3 /[C 4 mim]Cl (iron(III) chloride with 1-butyl-3-methylimidazolium chloride) ionic liquids. The temperature dependence of the Raman spectra of the FeCl 3 /[C 4 mim]Cl ionic liquids was measured for the first time to analyze their ionic species. In addition, the infrared spectra, thermodynamic properties, and freeze-fracture transmission electron microscopy were combined together with the Raman spectra to reveal the microscopic information of the

Styrene polymerization efficiently catalyzed by iron-containing imidazolium-based ionic liquids: Reaction mechanism and enhanced ionic liquid effect

“…First, the catalyst solutions were investigated by ESI(−)-MS and the [Fe 2 Cl 7 ] − anion was found in a dynamic equilibrium (Fig. 4-I) with [FeCl 4 ] − + FeCl 3 as we have previously demonstrated [19] and confirmed elsewhere [29]. Fig.…”

Iron‐Based Imidazolium Salts as Versatile Catalysts for the Synthesis of Quinolines and 2‐ and 4‐Allylanilines by Allylic Substitution of Alcohols

“…2-(1,3-Diphenylallyl)-N-methylaniline (4aa) 2-(1,3-Diphenylallyl)-4-methylaniline (4ab). [14] Orange oil; 1 (11). -2-(1,3-diphenylallyl)aniline (4ac).…”

“…The combination of the imidazolium chloride and iron(III) chloride in a 1:1 ratio provided the corresponding ionic liquid with the anion [FeCl4] -, as described by different groups. [8,11] Next, we studied the catalytic activity of these IBLAILs I-V in the allylic substitution reaction onto allylic alcohols. Herein, we report the results obtained from this study.…”

The Biginelli Reaction with an Imidazolium–Tagged Recyclable Iron Catalyst: Kinetics, Mechanism, and Antitumoral Activity

“…The ionophilic ligand (MAI·Cl) was obtained as previously described. [30] MAI·Cl was directly treated with [31] Catalyst performance: Traditional conditions for the Biginelli reaction commonly require large excess of one of the reagents, large amounts of catalyst, high temperatures, several hours of reaction, and occasionally the presence of a co-catalyst. [32] In an attempt to find milder conditions, the activities of the new catalysts were tested in several organic solvents and ILs.…”
