“…The alkylammonium 4toluenesulfonate salts do not yield positive ion mass spectra under normal electron-impact and chemical ionization conditions. By fast atom bombardment a series of cluster ions of the type [(AB)nAHz]+ (A = cation; B = anion; = 0-4; x = 0-2) characteristic of the salt are generated (15). For most salts the base peak corresponds to the cation.…”

“…Recently, information on the ability of ILs to give supramolecules has been obtained also for the gas phase by tandem mass spectrometric experiments. Mass spectrometry was successfully applied to ionic liquids more that two decades ago; however, only recently it has been possible to prove and characterize the existence of aggregates of these derivatives in solution with electrospray ionization mass spectrometry (ESI-MS) . In virtue of the gentleness and efficiency by which the ions are formed and transferred into the gas phase, the ESI technique has greatly expanded the range of molecules that may be analyzed by mass spectrometry to proteins, nucleotides, fullerenes, synthetic polymers, transition-metal complexes, and loosely bounded aggregates.…”

Development of Cation/Anion “Interaction” Scales for Ionic Liquids through ESI-MS Measurements

Electrospray ionization mass spectrometry applied to ionic liquids allowed the study of loosely bonded supramolecules, originating from these organic salts. Based on the observation that ionic liquids formed cationic [C(q+1)X(q)](+) and anionic [C(q)X(q+1)](-) supramolecular aggregates, we have investigated mixed networks, formed by different cations coordinated to a selected anion or by different anions bonded to a given cation, i.e., [C1...X...C2](+) and [X1...C...X2](-), with the aim to build a scale of the cation-anion interaction strength. The qualitative order of intrinsic bond strength to Br- was found to be the following: [emim](+) > [bmim](+) > [mor1,2](+) > [hmim]+ > [omim](+) > [mor1,4](+) > [bupy](+) > [bpyrr](+) > [picol](+) > [bm(2)im](+) > [TBA](+). Similarly, the interaction energies to 1-butyl-3-methylimidazolium (bmim) species envisaged two classes of anions: species tightly coordinated to the cationic moiety that include CF3COO(-), Br(-), N(CN)2(-), and BF4(-) and anions loosely interacting with the alkylimidazolium species such as OTf(-), PF6(-), and Tf2N(-).

Pentafluorosulfur(VI) bromide (SF 5 Br) adds to olefins of the form CX 2 =CX 2 , where X= H or F, with the pentafluorosulfur group usually adding to the carbon with more hydrogens attached to it. This series of compounds was used in an attempt to prepare the corresponding sulfonic acid hydrates of the general formula SF 5 CX 2 CX 2 S0 3 H·nH 2 0, in order to have these compounds tested as possible fuel cell electrolytes.The reaction scheme involved reflux of the SF 5 Br adduct with an equimolar amount of sodium sulfite in 50% ethanol for two days, followed by acidification of the recovered solid material using HCl or H 2 S0 4 • 2 Upon removal of the solvent, sublimation of the solid residue gave the acids SF 5 CH 2 CH 2 S0 3 H and SF 5 CHFCF 2 S0 3 H·H 2 0, while SF 5 CH 2 CF 2 S0 3 H·H 2 0 was recovered as the major component of a binary mixture. The sodium salts corresponding to these three acids were also made by neutralization of the acids with sodium hydroxide. For the other two members of the series, SF 5 CH 2 CHFS0 3 H was identified as a minor component of its product mixture, while SF 5 CF 2 CF 2 S0 3 H was not recovered at all, possibly due to a redox reaction in which SF 5 CF 2 COOH, sulfur, and bromine were formed.The acids could not be isolated from these last two product mixtures.The addition of Pentafluorosulfur(VI) bromide to CF 2 =CFBr was used to prepare a new adduct SF 5 CF 2 CFBr 2 and telomer SF 5 (CF 2 CFBr) 10 Br. Also, addition of SF 5 Br to CF 2 =CF 2 under mild conditions was found to produce good yields of the monomeric adduct SF 5 CF 2 CF 2 Br, where previously the reaction had produced a telomer.The compound SF 5 CHFCF 2 S0 3 H·H 2 0 is currently undergoing preliminary testing as a fuel cell electrolyte.Infrared,

Fast atom bombardment mass spectra of some alkylammonium 4‐toluenesulfonate salts

Abstract: The fast atom bombardment positive ion mass spectra of low molecular weight alkylammonium 4-toluenesulfonate salts are dominated by cluster ions of the type [(AB),A]+ or [(AB),H]+, where A is a cation, B an anion, n an integer from 0 to 4. With one exception the base peak is the cation A+.
