A cesium-133 nuclear magnetic resonance study of the cesium cation complexation by macrocyclic polyethers in hydrophobic RITLs

Thermodynamic data for cesium complexes formation with 18-crown-6 (18C6, L) in five hydrophobic room temperature ionic liquids (RTIL): trioctylmethylammonium salicylate ([TOMA][Sal]), tetrahexylammonium dihexylsulfosuccinate ([THA][DHSS]), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]), 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([BMIM][N(Tf)2]), 1-hexyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([HMIM][N(Tf)2]) as well as with 12-crown-4 (12C4, L) and 15-crown-5 (15C5, L) in [BMIM][N(Tf)2] are measured with NMR 133Cs technique at 27-50 C. Only [Cs(18C6)]+ complexes are found for [TOMA][Sal], [THA][DHSS], [BMIM][PF6], while in [BMIM][N(Tf) 2] and [HMIM][N(Tf)2] both [Cs(18C6)]+ and [Cs(18C6)2]+ species are formed. For 12C4 and 15C5 only [CsL]+ species are registered in [BMIM][N(Tf)2]. For [BMIM][N(Tf)2] the log K1 values are steadily increasing: 12C4 < 15C5 < 18C6. A comparative study of [Cs(18C6)]+ stability in RTILs is estimated to be in the range between water and acetonitrile with constants increasing in the order [THA][DHSS] < [TOMA][Sal] < [BMIM][PF6] < [BMIM][N(Tf)2] < [HMIM][N(Tf)2]. It is demonstrated that unlike hydrophilic RTIL the entropy change with an exception of [BMIM][PF6], promotes complex formation while the corresponding enthalpy change is either positive or gives rather small contribution to the complex stability. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
